### ⭐⭐⭐⭐⭐ worth it
*by A***R on 30 June 2026*

truly made a difference. 3 months in and still super soft and comfy, very much worth it.

### ⭐⭐⭐⭐ Not 10cms thick. But still lovely!
*by T***N on 18 August 2026*

Blissfully comfortable and makes such a difference when put on top of my old mattress. I’m very happy with it but it’s nothing near the 10cm thickness claimed in the listing; it’s more like 5cms. Still a great buy though!
