Updated: Full review two years later! (Preliminary Review: Unboxing and set-up)
I will write a full review of this bed frame after I have used it for a while but wanted to give a preliminary review first. I've had it for about a month before setting it up (waiting to get a new mattress and get rid of my futon), so it's been in the box which was on the large side but was able to tuck it away in my kitchen for a few weeks. I live on the third floor of an apartment building and while the box was a bit bulky and heavy, I was able to get it up to my apartment by myself with no problem. I'm a big girl with a not-so-great back, but it was definitely manageable. Having forgotten anything I read in the reviews about assembly, I was expecting a cumbersome set-up job with a lot of little parts and pieces and metal clanging around as I jostled this frame around my tiny little one-room apartment. I was pleasantly surprised to find that the frame consists of two separate pieces that fold out, and are then joined together by two screws in the middle. THAT IS IT!! Putting it all together took me about 20 minutes. Probably would have been less if I had more room and wasn't having to rearrange other furniture almost every step of the way. I have my new mattress set-up on the frame and expanding now (I got a Tuft and Needle original mattress which is a little longer than the frame, so not sure if that's a frame issue or mattress issue, but hardly noticeable) and was impressed with how easy it was to move the frame during the unboxing of the mattress and how lightweight it is. I am honestly a little apprehensive about the two pieces of the frame staying together with two screws as the butterfly bolts don't screw as tightly as I would like. I anticipate maybe having to find a washer or nut or something else to just make sure the fastener doesn't come off, but that's super easy so I'm not too worried about it. I did really appreciate that the hardware (two long screws and two butterfly bolts) came in a package together so it was easy to set them aside and not have to worry about them flying around. Oh! I also really appreciate that the frame came with two non-slip pads that are often used for carpets. That will hopefully help prevent the mattress from slipping off the frame. The storage capacity underneath this frame is AMAZING! Because there are two braces in the middle of each section, the storage underneath is in two sections divided horizontally but I can fit so much stuff under just one section because of the height which I am loving in my small apartment. The stuff from under my futon is now under ONE section of this frame, leaving me so much more room to store things that have been getting in the way. I will give it a full review after sleeping on it for about a week, but I'm optimistic that I will be highly satisfied! ****UPDATED REVIEW**** Two years later I am back to finally update this review! And two years later I am still 100% satisfied with this bed frame! When I moved last summer (Aug. 2020), taking this apart on moving day was a snap and it took me five minutes to set it up at my new place. I had previously been worried about the two screws joining the sections coming loose but that has been a non-issue in the last two years. I eventually added a bed skirt to help conceal the totes and things I have underneath, but the storage space has been such a game-changer for me, even when I moved to a bigger apartment. The frame is super quiet and holds up with some company in the bed, so no complaints there! ; ) I really cannot recommend this frame enough, it is one of the best Amazon purchases I have made. If you're looking for something sturdy, easy to put together (seriously only like FOUR PIECES in total!), excellent under-bed storage, and durable, GET THIS FRAME!

Wonderful bed frame.
For reference, I've owned this bed frame for almost 5 years. I came back to write a review because I like it so much. Pros: - easy to install - I love the recessed feet so you don't bang your toes on them. I've never hit my toe on the feet of this bed. - extremely sturdy. We have a full latex mattress that weighs over 200 lb in addition to both me and my wife sleeping on the bed. It's never bent or deformed in any way. - The underbed storage is great. There is plenty of room Cons: - I haven't found one yet Is it a decent value for the money? Absolutely. This would be my go-to if I ever needed a new bed frame. Is it durable or decent quality? Very much so. It's less expensive then many others but feels top-notch. Is it easy to use? Very easy to put together and set up. Does it match the description/photos? Yes. It looks very nice and just like the description photos. Color was exactly what I thought it would be. Does the bed slide on the frame? Surprisingly, not at all.

Absolutely perfect. If you're looking for an great, sturdy platform w/storage space; this is it.
Excellent value for the price! I scavenged through the reviews on this for hours and went back and forth on if it was worth it. I'm incredibly pleased I ordered this. My husband and I have an extra bedroom that was full of totes and boxes from our recent move. We bought the 18 in bed to have room four our 16-17 in totes. Not only did we clean our entire extra room out, now we don't have to look at the totes/boxes! ASSEMBLY: SUPER EASY. Put this together with my husband in under 5 mins. It was kind of hard to get the legs to lock into place, but that could be because I have zero upper body strength. His initial thought was, 'well this is going to be flimsy,' but steel is STEEL people. I'll get to that in a minute. All pieces were included, nothing was missing. MATTRESS: I'm using the queen size Purple mattress with this bed. It does slide around a bit, so we are planning on getting something to put under it. We aren't able to feel the bars of the platform at all. This is something I was incredibly worried about. SUPPORT/STRUCTURE: Between my husband and I we are putting about 450 pounds on this platform and haven't had any issues. No bars bending, no worrying if it's going break. I also ready reviews about this platform squeaking and people buying extra pieces for the screws. We didn't have to do any of that. This platform is completely silent, which is a nice change from our box spring that used to sing a symphony when you got in and out. Now we make jokes because we won't know when we are getting in or out of the bed. hah. Overall thoughts: If you're looking for an great, sturdy platform w/storage space, this is it. Our comforter is over sized and hangs over the edges, meaning we never see all the totes we shoved under there. I also love being up higher off the floor. This is a couple inches taller than the previous box/bed combo.

Dog Cave
Love, Love, Love the new bed we have put together! I mean LOVE!! The family does too! Everyone wants it now! hehehe!! We built it on this 18" foundation in a king size. Then added the Zinus 12" memory foam mattress which was wonderful , but we wanted extra plush so we also added a memory foam topper, and enclosed both in a mattress protector, and topped that with a quilted mattress topper then sheets. There is absolutely NO need for a box spring! Bedside steps yes, (with a 12" mattress , and topper our bed is 33 inches tall, and I am 61 inches tall! hahaha!) but no boxspring. With all the money we saved we also purchased brand new pillows(6), sheets, & pillowcases! My better half & I have been together for forever now, & have always had queen size beds. **The very first reason being costs! Don't ever believe they "gave" you the boxspring for free either. You get charged for it with the mattress - already included in the price. Raising a family can get really expensive! Which is why we have always gone for the Queen size; However now that our oldest has left home, & the fact that we can knock off the price of a boxspring using this foundation/frame we finally went for the upgrade, & couldn't be happier!! **I should mention this foundation works with boxsping mattresses as well, so even if you are just in need of replacing a boxspring - this will work for you, & support your mattress as it should be. **The space underneath is incredible!! I saw the numbers online (17" of storage space, the other 1 inch being frame), and was well aware, but in person all assembled? WOW!! It's a crazy amount of space!! Currently because we have not as of yet bought the storage tubs to put under the bed have a 125lb dog that keeps climbing up under there to sleep like it's his own little cave, if that gives you any idea how big the space is! **We did order the frame a few weeks prior to the mattress (if we had to we were going to buy it piece by piece), and stored it in the box it came in at the foot of the queen size bed in our spare room. Even though we were upgrading to a king bed it didn't hang out at all. Matter of a fact if we had had to store it in our room then all we would have had to do was to pull our queen bed a few inches from the wall, and slid it behind the headboard until we had the new mattress. We were surprised by how neatly packed, and easily managed the box was. You may however want to check the shipping weight if you plan on handling it alone just to be sure. **Setting it up was a breeze. Any adult within reason can handle it. If you can put a bookcase together then you can put this together. Well, I think that about covers it! **We DO recommend this frame, and hope our review was helpful!

4 Stars ⭐️⭐️⭐️⭐️ but still squeaks 🔊
I ordered this metal foundation to replace my box springs and for the under bed storage. ASSEMBLY: It took me less than 2 minutes to put together. And YES, I am a female and I did it by myself LOL. It was literally (2) screws you have to un/re-screw and then (2) that you insert that comes in a little baggie. The hardest part of the assembly is realizing that it's really super simple to put together. I personally was confused, "That was it." UNDER THE BED STORAGE: Tthere are 12 bars that keep the foundation up. 3 on each side (which is 6 total) and 6 in the middle. So you have those bars in the middle stopping you from sliding something big underneath it. For example, you can not slide a mattress the same size underneath it because the bars will be in the way. You can only fit 1/6 of the space under the bed in each section. But heck yes, to 18 inches of space up and down. I put lots of storage bins underneath it, it's really a game changer for your storage needs. NOISE-FREE??? Okay, so the first week or so, zero noise at all. I am a "Plus-size" woman (for now) and I don't move around a lot during my sleep but I do like to flop in the bed. I'm sadly sleeping alone (is this TMI yet lol) but I do utilize both sides of the bed as I like to sleep randomly. After the noise-free week, I got some squeaking that led to more squeaking. It's only when you first sit on the bed and not when you have your weight on it (so when you move around there isn't any squeaking). But the description does say no squeaking and if you want noise-free, I would say this is 95% accurate. OVERALL I would recommend it because who doesn't need more space?! If you can get over the random squeaks it's not that bad at all. It's 99% better than those old metal frames for the box springs. If you're still sleeping on a box spring, I would recommend you to buy this ASAP. I've pressured everyone around me to buy one too LOL. It also makes your mattress more even in the middle because it provides 360 support. I hope this helps, happy sleeping nights :)

Deluxe option perfect for my extra heavy body and additional weight from dogs
My review is for the FULL sized, DELUXE option. I read through many reviews across multiple brands of foundation/frames. I looked for information pertaining to the durability, sturdiness, longevity of each with particular interest toward reviews that mentioned heavy individuals that sleep with big dogs. Specific, I know. Seems that ALL of the foundation frames have a rating for well over a thousand pounds. Feeling better about my 300lbs, I figured I would be fine with any one of them, even when including the weight of my mattress and that of my two big labs. YET, so many people mention creaking beds, frame pieces that bend, etc and they are normal to light weighted people. So I jumped from product to product trying to find something I thought would be a good purchase. If not, my plan was to use a typical frame and box spring. When I came across THIS product, I saw that they recommended their "Deluxe" option for heavier individuals. "Reinforced stability with t-shape leg construction and locking system / Best fit for larger than average weight people" Ok, no matter how I spin it, that is me. I still hemmed and hawed, especially when I saw other products at least resembling it-- but that didn't mean it actually was the same product. I went ahead at put it in my cart while I took another peek at the perks and details. Clearly I went ahead with it, paid the extra for the Deluxe. Maybe the regular would have been fine. Maybe the Deluxe could have been a waste. My experience so far has been stellar, so I am very pleased to have plunked down the extra cash to buy the DELUXE option. --Design- legs set back so as not to smash your toes. I wouldn't have thought about it except some reviewers mentioned it (thank you reviewers)! The recessed legs are a safety and comfort feature. If you have stubbed your toes on a bed foot, know that this thoughtful feature will be greatly appreciated by all who walk near the bed. (again, Deluxe frame) --Ease of "assembly". I put that in quotes because it isn't much of an assembly needed. The frame comes in two narrow cot sized frames. These are set up super easy by just unfolding and straightening out the legs. The legs just need to be attended to by hooking a stabilizing arm and tightening a wing nut. Do this for all, then flip upright and put into position. Even easier is connecting the two frames to make one full sized frame. Bold and nut are provided. All done! --If you want more detail, look further down the product page to "Technical Specification". You will find a highlighted link that will open a User Manual. From there you will quickly see what needs to be done. It takes barely any time. I even had cats and dogs trying to "help" me in a small space and it added no time. --Sturdiness: My full sized bed is set up on a carpeted floor. I imagine that makes a difference, but I do not know. The surface of the frame is smooth- no pointy, sharp edges, so there was NO issue with it catching the material of my mattress. I don't recall if that was ever an issue here, but I recall seeing it across several reviews perhaps from other brands. --I have been using my bed nightly for a month. My two labs and sometimes a few cats join me- no creaking or unwanted movement. My husband and I have two full sized beds set up side by side to accommodate our large furry family, and to allow for better rest, yet he occasionally also um.. "joins" me, (and I know you know what I mean). No issues there either. Bed is still standing firmly in place! --I totally love the space under the bed. So do my cats, and at first, so did my dogs. It was this mysterious magical land to be explored. I don't really use it for storage at this time, but I like the option. All my pics include my curious menagerie. Orange cat, Charlie demonstrates difference in height (floor clearance) from typical frame to this frame. Huge difference! While my husband also has a full sized bed, his is currently a typical low frame, with a box spring, and topped with a mattress. Mine is this tall frame and a hybrid mattress (that comes in a box), and all together, side by side they are the same height. I hope to replace his with exact same set up as mine, eventually. So far, I am super pleased with this frame. I keep up with my reviews and will definitely come back if I have any further thoughts, revelations, problems, or even to just say it is still going well.

PERFECT for Storage + Completely Silent + SOLID Quality Steel Construction
Sturdy, affordable, completely silent and the PERFECT solution for under bed storage. I purchased the Queen sized mattress base which allows for appx. 17" of storage height underneath. One of the photos in the description shows the height with an arrow showing the 14" then 'up' 4" and I was left with the impression that the bed had adjustable legs. It does not have adjustable legs, but since I expected to leave it 'adjusted' to the full height anyhow, I wasn't concerned either way. The bed assembly took all of 15 minutes and the steel is solid and sturdy with absolutely zero squeak. The legs are capped with plastic covers so no scratched floors. The legs are also recessed about 5" from the corners to save your toes from being mashed when you walk around the bed, which is an exciting change from my traditional bed frame (my mangled toes thank you, Zinus). I have a 10" memory foam mattress and the height is just right with my height at 5'2". STORAGE! I am able to fit a two Sterilite 66 qt Clearview totes (23 5/8" L x 16 3/8" W x 13 1/4" H) next to one another under each quadrant of the Queen base with room to spare above and in front of each tote (again, no mashed toes) OR three stacked under-bed storage totes (generic sized, no wheels) under each quadrant. The space above the Sterilite tote is sufficient space to store a queen sized blanket and the space in front is room enough for two size 7.5 shoes sideways. The under bed totes have no room above and come to the edge of the bed frame with no extra room. There is also additional storage space between the leg and the appx 5" recess against the head of the bed (which for me is the wall; no headboard); we found that standard sized shoe boxes fit perfectly here. NON-SLIP PAD: Several of the reviews mentioned needing the non-slip mat between the mattress and the bed. I have found that it is not necessary and the mattress does not slip or move while in use. However, with a little effort, you will be able to 'slide' the mattress, similar to a traditional mattress, in order to make the bed. I was concerned at first about not having a buffer between the steel and the mattress and the rungs causing damage or indentations. I'm relieved that this hasn't been the case. I'm sure this can vary based on mattress brand, but it hasn't been an issue for me with my Lucid 10" memory foam mattress. By the way, the Amazon base does not come with the non-slip mat, though I believe it does with the direct purchase from the Zinus site. EXTRAS: I can easily see packing and using this frame for an extended camping trip with an air mattress or having an extra base stored for when company visits. It folds down quite compactly, which you'll notice clearly upon delivery. I personally think the twin would make an exceptional foundation for seasonal (no precipitation) deck seating/lounging and the storage underneath is perfect for outdoor items. So overall, I'm beyond thrilled with the quality and performance of the Zinus SmartBase Mattress Base. I've recommended it to anyone who'll listen to me sing the unending praises of a mattress base (surprisingly at least a dozen) and will not hesitate to order another should the need arise. Very highly recommended!!

Durable bed for bigger people!
I bought this Cal King bed frame in 2017 and it is still going strong! I love that the legs don't stick out like other bed frames so I don't hit my toes. I love that it is high enough to put plastic totes underneath it and cleaning is also easier because the bed is high. The only thing I will say is that maybe 2 or 3 times I've had to tighten the screws that hold it in place when it's open but you don't need any tools to do it. I was able to fold it up and fit it in the back of a Nissan Rogue and move it from SoCal to NorCal. I will say that it is VERY light! Which is great but also can move around a bit if you don't have it on carpet. I didn't mind that at all because it was so easy to move to make my bed on tile floor. It does squeak a bit now but I'm sure it would be resolved if wanted to put in the time to maybe add a little WD-40 to the screws or something. I highly recommend this bed frame! Oh and we are not small people so it consistently had had probably 500 to 800 lbs on it regularly. I just bought a Queen version for my mom. There are many knock offs but I can say this one is it!

Meets all the manufacturer's claims
EDIT 2: Feb 2019 I've had this frame for well over a year at this point, and it's still fantastic. I've moved, and disassembly/reassembly literally takes seconds. Still as sturdy (and COMPLETELY SILENT) as the day I bought it. However! The price has nearly doubled! I purchased this frame at something like $110 taxes in. Now I see it being sold for $200?!?! Do I recommend it? YES! Would I have paid $200? Not a chance. I would be looking at Zinus' own website, or find some other supplier if the price is this high on Amazon. This frame is awesome, and 100% worth having, but wow, the price doubling is not cool in my opinion. EDIT: 3 Months After Purchase Still no issues. Its still solid, it's still silent. Really glad I bought this frame. I may make a headboard or something when I have more room, but for now it meets all my needs and I love it. I just put this frame together, and I have to say, the reviews seem accurate so far! It takes 10-15 minutes to assemble by yourself, maybe less if you have a friend to help. Although the legs already have rubber caps, I placed them on rubber glides for extra support on my hardwood floor, and so far it feels sturdy and makes absolutely no noise at all. My only small complaint is that there was no hex key included in the package to help you tighten the bolts holding the two halves of the frame together, but since I have plenty of tools, it was really a non issue for me. There's plenty of space beneath for storage, and so far I'm very happy with my purchase. Obviously, if I have any troubles, I'll come back and update this review, but for now, in terms of meeting the product's claims, value for money, and ease of assembly, I feel this frame deserves the full 5 stars!

Practicidad 100%
Compre la base King Deluxe, para mi colchon King Size y le vino perfecto, le queda grande o sobrado al colchón por no mas de 5 cm de cada lado, ya con el edredón la verdad es que ni se nota y mucho menos lo sientes por que no te golpeas, el armado es la cosa mas fácil y practico del mundo, no demoras mas de 10 minutos en armarlo, el resultado es que te sorprende de lo práctico y resistente que se siente. Por último, la base es alta, lo que te permite guardar un maleta sin problema, lo que lo hace todavía mejor.

Sturdy, silent, easy to use
I have always just put my bed on a box spring on the floor, but I felt I needed more storage in a small living space so, after some looking around I bought this. I had, at first, been hesitant about a metal frame because they are usually so unstable and tend to squeak with every movement. I always slept like crap on metal frames because I am a light sleeper and need a good amount of back support. But the frame had good reviews and was incredibly cheap compared to more fashionable wooden frame options. Too my delight, I found that this frame has none of the problems I was concerned about. It's really light and easy to put together - essentially, the legs just fold out and latch into place. That doesn't sound like a sturdy setup, but trust me, it is; the metal is very thick. The entire thing folds together for easy moving if you need it. I honestly think you could even use it as a camping cot with a blow up mattress and something to put between it and the slats, simply because of how light and easy it is to move. If you're looking for a quiet metal frame with lots of storage space underneath, I'd absolutely recommend this one. My housemate ended up going with a slightly different model from the same brand and she's very happy with it as well.

Great bed frame.
We love our new frame....it's perfect. It was very easy to assemble...it came in just two sections that get bolted together. Even our cats love it cause now they both fit underneath it.
