Slumberland mattress review

The Copper Seal is a lot of bed for the money and extremely comfortable

This mattress was reviewed by Which? in June 2018.

It received a test score of 66%. They were impressed with how the mattress performed across all tests


The Slumberland Copper Seal mattress has 1600 pocket springs in a king size mattress. Three layers of foam complete the comfort layer. Although the comfort rating is a medium feel, testing assessed it as feeling on the softer side of medium.

What will it be like to sleep on?

The mattress offers good support for side and back sleepers alike. The mattress absorbs movement well and is easy to turn on and you’re unlikely to disturb your partner. It’s breathable and doesn’t feel warm, so you should enjoy a dry and comfortable night’s sleep.



Anything else

It’s unlikely to get softer with time but might lose loft. It’s a one side pocket sprung mattress and with side handles is easy to rotate. In a 2019 survey, members that owned a Slumberland mattress generally find them very comfortable.


A decent mattress with no major faults.
