## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to fit
*by J***) on 4 April 2025*

Does what it says on the packaging.

### ⭐⭐ matress topper
*by B***R on 15 February 2025*

the plastic zip keeps pulling appart

### ⭐⭐⭐⭐⭐ Great quality, and delivers what it promises
*by K***R on 14 August 2019*

Came in a big Swiss roll shape wrapped in plastic and in a zip up bag (now being recycled for storing stuff, even that's good quality!). Hard to get out of packing as it's a snug fit and a bit heavy... But unrolled on the bed fine and as I hadn't thought to check the instructions I only left it am hour before making the bed, ah well!Anyway, it's lovely!. I wouldn't say it's like a squishy mattress topper, it's almost a little firm. But it's so supportive on the body and feels very comfy to lay on. Definitely also keeps me at a comfy temperature, I don't overheat, but I'm also not chilly (as I feared I might be!). Have slept really well using it, mainly because I don't wake up early hours overheated etc.Would highly reccomend it if you need a supportive topper that helps you have a comfortable and not overheating night.
