The springs are zoned to provide targeted support to key points such as the hips, back and joints - just where most of our customers report needing it most.
Plush, sustainable fillings
This mattress also features a comfortable pillow top, filled with Eco Comfort Fibres™. Eco Comfort Fibres™ are soft, highly breathable and sustainable, meaning they are low impact on the environment.
The healthy choice

Haven't slept in it yet so basing the rating on experience of a double mattress of same type purchased last year. That one is very comfortable. Very prompt delivery service - could only have been better if we lived next door ti the warehouse!

Always great service from these guys, ordered Sunday and delivered Monday as they said they would. We have been using these for years and wouldn't go anywhere else now. Also a great mattress for the price as well.

Great quality and a fair price

Actually very firm. I've had Silent night medium firm before and it was really comfy. After a few weeks I added a topper to this and still wake with pains in my hips. Perhaps not ideal for side sleepers.
