No, Helix mattresses have great cooling performance and do not sleep hot. We’ve personally tested the entire Helix lineup, 22 mattresses throughout their 3 price tiers – Standard/Core, Luxe, and Elite.
Every single Helix mattress has above-average cooling performance, compared to the average (based on 400+ tested to date)
All current Helix mattresses have a pocketed coil base and a foam comfort layer. The exact composition of the foam layers varies between model, but essentially it’s a mix of memory foam and poly foam.
In terms of cooling, pocketed coils are one of the most advantageous materials a mattress can have.
Concerning foam, poly foam will generally be cooler than most memory foams. But memory foam that is infused with gel, copper, or graphite have also noted better cooling performance across our tests.
They also have an optional enhanced cooling cover, which comes standard on the Elite models. You can add this cover onto the Base and Luxe models for approximately $200. It does make a difference, as we saw on the Helix Sunset. We added that cooling cover on this model and it noticably outperformed the other core Helix models.
