Does what it says on the packaging.

the plastic zip keeps pulling appart

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.

This is firm and gives excellent support. Fitted perfectly on king matreess which has seen better days. This will mena I can get another 18-24 months out of my matress so gives time to save up for that bigger purchase so worth the money. Has immediately helped my lower back which I hadn't really noticed was suffering due to soft mattress.

Very disappointed it was initially comfy but within days of sleeping on it, it makes you bothe roll to the centre. Without the topper this doesn’t happen.

works well
