Extra deep mattress topper

Yes, I recommend this

I bought this to cover my uncomfortable sprung double mattress rather than buy a new mattress. It has worked to some extent, but isn’t as soft as I had hoped it might be. I can’t feel my mattress anymore so the mattress topper has been successful. It’s kept in place by corner elastics that go over the mattress corners. I also use my mattress protector on top of the topper as it’s easier to wash. I thoroughly researched mattress toppers and chose this based upon materials, depth of topper, price and reviews. I would say for the price that it has been a successful purchase.

Light as a cloud..

Yes, I recommend this

I feel like I am sleeping in a hotel bed, but actually factor it’s my bed and this deep mattress fits the bill, I can’t wait for bed time with my Egyptian sheet, duvet and pillow cases- feel’s wonderful, the softness of those sheets against your skin, plus the hotel pillows that I brought- Perfect combination nice n fluffy!! This topper is a must for 😉😁

Good value

Yes, I recommend this

Deep and soft when put on the bed but doesn’t hold its depth when sleeping on it. Good value compared to others we looked at but not what I hoped for.

Great Topper

Yes, I recommend this

We purchased this to use on a sofa bed and it didn't disappoint our guest who slept on it for a week. Good quality and usual great service from M&S. However, Evri has quite a way to go around service and really would prefer M&S not to use this delivery company.

Good quality for the price.

Yes, I recommend this

Pleasantly surprised how much extra comfort it gives on a hard orthopaedic mattress. Definitely felt much warmer, so dubious if I could use it in the summer months. Overall I’m pleased with it and feel sleep quality has improved.

What a great buy. This is the best thing I’ve bought for the bed. It’s such great quality, nice and thick. I’m a side sleeper and my hip joint suffers quite badly when sleeping….but with this topper I slept all night.
