Very firm and good to sleep on, great delivery and only problem I had was shrunk when you fold and sit on it . When you are not using need to fold and keep if not need to spread it out. But quality is very good, easy to move around the house for movie night. Anonymous. Tue Apr 21 2026

15cm, Double (4'6)

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

Comfy and great for my little boy. Not as thick as I was expecting and if you are slightly heavier then maybe not the best. Gabrielle. Willerby Hull, GB. Mon Dec 15 2025
