Indulge in a restful and rejuvenating sleep with our memory foam mattress. Medium Comfort is supportive for most body types and sleep positions. Too-soft mattresses don’t give proper support and can cause back problems in the long run. Too-hard mattresses don’t provide pressure point relief. The sweet point is our medium mattress strikes the right balance between comfort and support and promotes better sleep.

Mattress is measuring at 11cm. Instruction booklet says read instructions carefully but there isn’t anything about the size changing. I’m hoping it will get bigger after a hour or 2. Anonymous. Sun Feb 08 2026

Very disappointing experience with Wayfair mattresses. I ordered two foam mattresses (king and double) and specifically explained to the phone consultant that I wanted something similar to a previous mattress I had purchased from Wayfair, which was good quality. Unfortunately, the phone consultant clearly did not understand the request and sent very thin mattresses – around half the depth and significantly poorer quality than expected. Both mattresses were completely unsuitable and had to be returned. I placed the order via phone specifically to avoid errors, as the exact SKU from my previous order was out of stock — making the incorrect items even more frustrating. The returns process was equally frustrating. I was told: - A direct replacement was not possible - I would need to accept Wayfair credit and reorder - Or pay a £40 return fee if I wanted a refund to my original payment method When I asked what would happen if the replacement was incorrect again, there was no clear answer or reassurance and I was. told nothing can be done then. At that point, I had no confidence in reordering. I chose to pay the £40 just to resolve the issue and purchased my mattresses elsewhere instead. Overall, very poor experience: Incorrect product sent Poor product quality Confusing and unhelpful customer service Unfair return charges Would not recommend.. Anonymous. Tue Apr 07 2026

I bought this for my teenage son. The under side (which is on the top in the pictures) is very filmsy! The mattress cover feels very synthetic. The mattress came rolled up and we left it for 2 days to stretch out (this is why it is upside down on the bed as it was curling up at the ends). After 1st day it looked 2 inches smaller than the bedframe, but now sits nicely in position. It is hard, but perfect for back and tummy sleepers☺. I would not recommend for other.. Annamaria.
