A better night's sleep.
Since receiving this topper mattress I've been sleeping more comfortable. I feel I do not want to get out of bed in the morning.

Memory foam mattress
I've had this mattress now approximately 8 weeks. It's ok, I. Still getting body imprint, so turning it every week. Not sure ill keep it, I'm only 9 stone, so don't know how you'd go on weighing anymore.

Alleviated hip pain
My hip pan has gone and I have much less discomfort in my shoulder since sleeping on the topper. The only thing I would say is that the corners are ‘squarer’ than my mattress’ which means my fitted sheets don’t stay snugly in place. Plus it does tend to move about on top of the mattress: every morning we have to lug it back up a few inches towards the headboard! All in all it was a good buy and cheaper than replacing our very expensive but twenty-five- year-old mattress.

Finally; a good night’s sleep!
It really has helped with my sleep and also with not feeling so achey in the mornings on my hips.

Makes a big difference
I am sleeping better on this really comfortable mattress. For this 81 year old a good sleep is hard to achieve. This makes a big difference.

They slip
Brilliant except they slip about ten inches off a double and a king size bed regularly. They don’t have corner straps to keep them in place . I’ve tried everything under the sun but we have to pull them ionto the mattresses some times twice a night. They fit on top of two Dormeo mattresses. I think I would have been better buying two new full mattresses. When they are still they are very comfy as are the full mattresses..

Avoid! Not worth the money
I hate this mattress topper and would have sent it back but it’s a super king and wouldn’t fit back in the box. The topper is sold as medium to firm but if anything it’s soft. It skids around the bed all night every night as it’s not possible to secure it to the mattress and it’s a poor fit and hangs over the sides of my mattress. I would not recommend this topper.
