Memory Foam Warehouse - 4FT Small Double 7.5cm (3") 75kg - Memory Foam Mattress Topper - Including FREE Coolmax Cover - 120cm x 190cm x 7.5cm

It's comfortable, but the cover is not worth £30 - it should be half that, and the bottom of it is made from smooth plastic which means it just slides off your existing mattress as soon as you move. It's too slippery for straps to help, so it just ends up being really annoying. It's also supposed to fit a small double bed (6'1" x 4'0") but it's actually two or three inches short in width and length so looks stupid. You can't get a normal fitted sheet over both it and the mattress, so the sheet is always coming adrift and ending up in a bundle next to you. It also gets really hot, so the "cooltherm" cover is probably just a gimmicky name for something that's not particularly effective. In short, don't bother, it's a pointless waste of money. Just spend a bit extra and get a complete foam mattress all in one piece.

very good product. bought this for our caravan where the front seats make into a bed with the materess on top it is really comfertable. very pleased and quick delivery.
