Great quality, comfortable mattress topper

Yes, I recommend this

Bought this on offer so got a good deal as it’s a high quality item. I had a really good sleep last night when using for the first time. It’s comfortable and fits the bed perfectly (double size), plus very easy to attach using the elastic “loops” at each corner. Very pleased with it and would recommend.

Wouldn’t buy again - probably over rated

No, I don't recommend this

Bought for comfort, but it’s only okay, there’s elastic bands on each corner to secure it in place, but it’s doesn’t prevent the topper movement while sleeping and tossing and turning, the elastic bands should go over the ends of the mattress and secured in place. The topper isn’t cheap, not the best value of money spent 😒 could not recommend

Good quality!

Yes, I recommend this

Good quality mattress topper for the price. Was quite firm so purchased a separate topper to go on top which seems to have helped with the comfort!

The mattress in our spare room was a bit hard, especially after replacing the divan base with a platform top one. This mattress topper has just provided enough give to make it feel more comfortable and enable a good night’s sleep. Very pleased with it.

Buy it!

Yes, I recommend this

I was surprised at how thin this was but don’t let this put you off! It has completely transformed my old horrible hard mattress which had the springs digging into my hips. This mattress topper has transformed my sleeping experience. It is incredibly comfy and I highly recommend it.

I could feel all the springs through my mattress but this topper has meant I can’t feel the springs any more. Very comfy and luxurious feel. Good value for money
