Sleep Cooler, Wake Refreshed
Wake up feeling genuinely rested...not sticky, stiff, or overheated. The Frostwell Cool Blue Foam Mattress tackles one of the most common sleep frustrations: heat build-up. The 3cm CoolBlue memory foam comfort layer actively encourages airflow and dissipates body heat throughout the night, so your sleeping temperature stays comfortable from the moment you lie down to the moment you wake.
Ideal for anyone who runs warm in bed, or who has found traditional memory foam too heat-retentive in the past.
Three Layers Working Together
Support and comfort don't have to be a compromise. The 14cm Eco foam base gives you a solid, resilient foundation that maintains its shape night after night. Above that, a 3cm reflex foam layer (Grade 33/190) distributes your body weight evenly, reducing pressure on hips, shoulders, and the base of the spine.
The CoolBlue memory foam on top then gently contours to your body, cushioning pressure points without that sinking, trapped feeling associated with denser foams. The result is a medium-feel mattress that works for side, back, and combination sleepers alike.
A Cover That Keeps Things Fresh
The distinctive circle-design zip cover isn't just good to look at - it's genuinely practical. Fully removable and washable, it makes it easy to keep your sleep surface clean and fresh over time. The hypoallergenic treatment makes it a sound choice for allergy sufferers too, helping to reduce irritants without requiring any special maintenance routine.
Delivered vacuum-packed and rolled, the Frostwell expands to full size within a few hours of unboxing ready to use the same day it arrives.

Do You Get Hot at Night? CoolBlue is, well, Cooler!
CoolBlue is excellent for people who like the feel of memory foam but want a more sophisticated foam mattress which responds faster and is cooler than standard memory foam, preventing those sweaty nights throughout the summer.
Temperature sensitive CoolBlue memory foam layer provides comfort and support to your shoulders, back and hips, and works in harmony with your body to ensure that you are sleeping in the correct anatomical position, meaning you can wake feeling refreshed and free of any minor aches and pains
What is EcoFoam?
EcoFoam is a sustainable foam made from 100% recycled and re-engineered materials. Designed to be durable and resilient, it reacts to body weight and movement to deliver firm, orthopaedic-style support - making it a practical choice for anyone who needs a stable, even sleeping surface. It's naturally dust mite resistant and hypoallergenic, so it works well for allergy-sensitive sleepers too.
Spring-free by design, EcoFoam mattresses are completely silent and typically come with removable, washable covers for easy long-term maintenance.
Density/Firmness Rating - What's Best For You?
Each type of mattress varies by comfort grade, from soft to firm. Our density ratings (provided by the manufacturer) are to be used as a guide. Every comfort grade has its advantages, and the right one for you depends on your personal preferences but also your favoured sleeping position.
The Frostwell Cool Blue Foam Mattress is rated as Medium
| Soft | Offers the least resistance, providing a gentle support base, contouring to your natural body shape. Perfect for side sleepers. |
| Medium | Gentle support system, conforming to the shape of your body. Great if you sleep on your side or front. |
| Firm | Provides essential support to maintain natural spinal alignment. Ideal for back or front sleepers. |
| Extra Firm | Provides increased support to maintain natural spinal alignment. Ideal for back or front sleepers. This extra support helps your body maintain good posture and prevents your back from curving. |
Unboxing
- This mattresses is rolled and vacuum packed, so should be removed from the packaging as soon as possible after delivery
- Once unrolled, please allow up to 24 hours for the mattress to fully expand and recover to its intended shape and comfort level
- During the first few hours, the mattress may feel slightly firmer than expected – this will settle as it fully expands
- Some customers may notice a slight, harmless smell when first opening the mattress. This is known as off-gassing, which is normal for newly manufactured foam products. The smell is temporary and typically dissipates within a few hours to a couple of days. We recommend placing the mattress in a well-ventilated room during this time to help the process

What you're paying
