If you’re dreaming of a mattress that keeps you cool, comfortable and supported, the TheraPur Glacier 3800 ticks all the boxes. A combined sleep system pairs pocketed and micro springs with ActiGel® foam and PurFibre® layers to support you from head to toe.

Our micro springs contour to every inch of your body, whilst individually wrapped pocket springs cushion your movement without disturbing your sleep partner.

And when it comes to cooling, we’ve got you covered. This mattress has refreshing ActiGel® foam stitched directly into the quilted top layer, keeping the cooling gel as close to your body as possible. Say goodnight to overheating.

Within the mattress, a 4cm layer of refreshing ActiGel® foam cushions your joints with instant pressure relief. The foam is divided into responsive zones, optimising airflow to keep your temperature comfortable.

Around the border, you can find even more supportive foam to maximise your sleep surface. Sleep soundly without fear of rolling out of bed, and enjoy its supportive feel every time you perch on the edge of your mattress too.

We’ve wrapped this mattress in a cosy ActiCool® knitted cover, expertly designed to prevent overheating. The pillow top surface gives you an irresistible sink-in feeling, with plenty of cushioned support.

Additional information:
