Very pleased with the product except for the fact that it has to be spot cleaned as I wanted to be able to machine wash it. I should have read the details more carefully before buying.

Bought to soften a very firm new mattress. It fits exactly on a kingsize bed held in place with the corner straps. Would recommend!

Well made mattress topper

Never used it yet . Bought it for my spare bed which has an expensive but hard mattress on it. It looks well made like the fact it is not memory foam and not too thick . A very good price as well.

This mattress topper is very comfortable and offers great value. Its zip cover means it can be used for holidays and is easily transported.

Comfortable but not necessarily cool

Originally posted on marksandspencer.com (UK)

I bought this mattress topper to add comfort to a very firm mattress. It does the job in terms of adding softness but I feel it may prove too warm in the Summer months but only time will tell. I would actually have preferred it to be less thick but more dense so I should perhaps have opted for memory foam instead.

Good Quality and Value

Originally posted on marksandspencer.com (UK)

Some time ago I bought a similar M&S mattress topper for another bed and the very favourable experience caused this purchase. It is early days yet but this product appears to be of similar quality. The online purchase was easy and delivery speedy but purchasers may prefer to examine the topper in store to know whether it appears suitable for them - people have such personal preferences in beds and bedding.
