Features

Medium to Firm

A suitable level of support for those who can’t choose between medium and firm, but want a comfortable mattress that’s not too hard

Cool Blue Memory Foam

Temperature regulating pressure relieving material designed to reduce tossing and turning for a cooler more restful night's sleep

Open Coil Springs

An interconnected spring system that is extremely robust and durable

No Additional Edge Support

Allows the mattress to be bent or rolled which allows for compact storage

Hand Tufted

Especially important for extra deep mattresses, tufting ensures the fillings are held securely in place, thus increasing the life of the mattress

Stretch Knit Fabric

A soft pliable cover that allows the fillings to contour your body shape for optimal comfort and support

Single Sided Mattress

No requirement to be flipped, simply rotate from head to toe 

5 Year Warranty

In addition to a 1 year guarantee, this mattress has a further 4 year manufacturing warranty for additional peace of mind

60 Night Comfort Guarantee

If you don't love your new mattress, contact us to arrange an exchange. A Protect-A-Bed mattress protector must be purchased with your mattress.

Vacuum Packed

This allows for easy transportation and when fully unpacked it fills out to its full and permanent size within a couple of hours

Description

Designed with comfort and hygiene in mind, the Cool Blue Memory Coil combines traditional Bonnell springs with the heat reduction properties of Cool Blue memory foam.

Its advanced Cool Blue layer has been developed to offer the same feel and pressure relieving properties as equivalent memory foam, but without the associated heat discomfort.

Cool Blue also features ultra-fresh anti-microbial, anti-bacterial and dust mite protection, plus excellent breathable properties for the ultimate in mattress hygiene. 

At the core of the mattress is a strong open coil interior that consists of hourglass shaped springs, set in rows running from head to toe and connected into one single unit by a spiral wire, known as a helical wire.

As its one-sided, it only requires rotating from head to toe. For easy transportation, it will be delivered to you vacuum packed in a roll and is an ideal solution where access is limited.

The Cool Blue Memory Coil super king size mattress is manufactured in the UK by Sareer and offers a medium support for a comfortable and refreshing night's sleep.

Somewhat disappointing, not much support, okay for a he occasional use in the guest bedroom, may suit a small child, but not enough support for an adult.

Son loves it, he finds it quite Soft but he did have a Firm Single Mattress before this. Will see in the Summer if it's colder than a memory foam - hopefully so.

Mr Thomas McMichael - 22 January 2024
The mattress claims to be medium to firm, it's not it's very soft. It's still comfortable but wouldn't say it was supportive so if that's your type of mattress then it won't be for you. It's for a spare bed so won't be used often so not dire but I wouldn't buy it for my own bed but if you like a soft mattress then it will be great. It's nice quality on the face of it just depends on your preference.

The mattress came in box like it said was easy to open and it unfolded and went into shape quite quickly, we thought we would do this 1st before putting bed together to give it time to unfold. My son loves it he is sleeping well on it. The memory foam is nice and soft.
