Hi Ravi,

Many thanks for your question about the coolest mattress types and fibres. It's a really good one we get asked a lot!

You're right to point out that memory foam and associated gel foam mattresses, like many of the boxed rolled mattresses, are incredibly heat retentive. Most of the new mattresses claim to be cooler than the last one. However, all foams will retain far more heat than a fibre or natural fibre mattress. This is because these moulding foams are vasco elastic so need to retain heat to work. Otty, Eve, Casper, Leesa and MADE are all constructed primarily of synthetic vasco elastic foam which all retain far more heat than say a wool based mattress.

If you're wanting to avoid overheating during the night a pocket spring and natural fibre mattress is the best route to go down. Natural fibres are high wicking and breathable. Whereas gel and memory foam mattresses are the least breathable. Regardless of what covers you put on them or new gels/copper/metals etc they mix with them. They will always retain excessive amounts of heat compared to a breathable mattress.

What's the best natural fibre cool mattress?

If you’re wanting a 100% natural fibre calico encased vanadium coated pocket spring mattress then have a look at our Artisan Bespoke 004 mattress. Completely breathable and high wicking, keeping you cooler in the summer months but also warmer in winter if it get a bit chilly. Also unlike boxed foam mattresses which are all one sided this is a two sided model. So effectively twice the sleep surface and lifespan compared to cheaper memory foam counterparts.

It has a medium feel in the natural upholstery with a forgiving top layer. Great for pressure points. The 1600 individual pocket springs allow restless sleepers to move quickly, easily and effortlessly. Often this helps reduce the amount of fidgeting when coupled with the progressive comfort layers of this mattress.
