The ActiGel® Glacier 4000 mattress is fresh and breathable, with TheraPur's coolest ever graphite-infused ActiCool®+ cover, perfect for sleepers who often overheat.
By reducing heat through the night, ActiCool®+ helps you fall asleep quicker and stay asleep longer, with exceptional heat transfer and moisture wicking.
4cm of zoned ActiGel® foam offers the pressure relief of memory foam without trapping heat, thanks to its smart temperature regulation.
Responsive pocket and micro springs absorb motion, so there'll be no more 3am wake ups when your sleep partner tosses and turns.
With a medium comfort grade, the Glacier 4000 is an excellent all-round choice as it suits most sleep positions.
All-new ActiCool®+ is infused with cooling graphite to eliminate overheating once and for all. It’s right at the top of the mattress, where you’ll feel it most, and totally free from chemicals for a fresh, natural night’s sleep.
