Product description:

A traditional open coil spring mattress made with quality 13.5-gauge metal springs. The spring system is encapsulated in layers of high-density support foam. The mattress is fitted with a quilted, breathable protective cover with stitched bound border support. This spring mattress is of medium firmness and has a bit more bounce compared to memory foam or pocket sprung mattresses which are firmer.

Note: As our mattresses are vacuum rolled, we advise 72 hours for the mattress to inflate to its full depth.

Super feature

Our mattress has a quilted cover to provide a flatter more comfortable sleeping surface as opposed to tufted covers, which may look posh but they can get uncomfortable. 

The mattress cover is made from breathable knitted fabric to promote air circulation for a more comfortable night's sleep.

The cover has stitched bound border support - support all the way to the edge!

What's Inside?

The traditional bonnell coil spring system is fully encapsulated in high-quality super thick super dense support foam. This is a special type of foam used in furniture manufacture to ensure longevity. 

Bonnell coil springs are thick hourglass shaped coils all threaded together to create a strong and stable support system. 



What we think

Sarah - Marketing: ' I have a couple of these spring mattresses on the harlow guest bed in my spare room. My friends who have slept over say they are really comfy, and i think they are great value. I love lounging on them when i am reading or chilling out. The firmness is about a medium, with a bit of springyness, so they are a good all-round mattress.'
