Cool & comfortable

Yes, I recommend this

A really comfortable mattress topper, it doesn’t make me feel hot - especially during recent hot weather - I have slept well. Bought it to prolong the life of our current mattress & it is definitely doing that.

Been using for a week and only complaint so far is it needs to be fluffed every few days to redistribute filling. It is so far comfortable and good it can be machine washed

Highly recommended

This is a brilliant mattress topper. It is well made with an outer cotton cover and it really enhances the comfort of our mattress. Study elastic straps keep it in place and it has been in use for several weeks now and I am still very pleased with it. I have never used a mattress topper before but I can highly recommend this one now that I have tried one. I was worried about how our standard depth fitted sheets would fit over the top but they still do without out looking stretched or too small.

So far it works well.

Yes, I recommend this

We were concerned that we’d never be warm in bed again using this but it warms where you’re lying but stays cool everywhere else so a quick shift in position soon cools you if you overheat. Only used for a week yet so can’t say how it will perform in the summer but we’re hoping that it will help us sleep better in hot weather.

Have a firm mattress and bought this topper to make it softer. No regrets, it’s lovely, certainly sleep better and would definitely recommend.

Comfortable and cosy.

Yes, I recommend this

After using the topper for one week, I can say it's very comfortable and feels like you're lying on a plump duvet. You forget your lying on a ultra firm mattress.

Good quality mattress topper

Yes, I recommend this

I purchased this to replace a cotton quilted mattress protector which had shrunk slightly, I'm very pleased with it, as now I can more easily turn the mattress around by its handles without having to remove the cover. I use a fitted bed sheet, and am pleased that the mattress topper doesn't move around under the sheet. Although our mattress already has a softer top layer, this mattress topper makes it feel even more comfortable. I particularly like that it's encased in good quality cotton rather than poly-cotton (or worse, all polyester). It seems to keep its 'loft'. I hope it will wash well, but time will tell. My only negative comment is that the product photo is not of this mattress topper. The photo shows wavy stitching lines, whereas the actual product has straight stitching going widthways across the topper. I doubt this makes any difference, but just makes me doubt whether M&S product photos are accurate.

Provides comfort and luxury for a firm mattress

Yes, I recommend this

Our new mattress was deliberately very firm to support our weight. But that made it quite unforgiving! This protector provides an inch or so of comfort for the “sink in” feeling in the surface. We also deliberately bought a wool mattress to help with the night sweats and so this “cool” protector would support that. We have not been disappointed. Sleeping like babies! I wouldn’t have paid £89 for ANY mattress protector but at £45 this was reasonable and has been worth the investment so far.
