The ActiGel® Polar 2800 Mattress is one of the more exclusive and premium mattresses in the Dreams lineup. Part of the Therapur range, this mattress has exclusivity and won't be found anywhere else. Not only are reviews mostly positive but the mattress has also won the award from Good Housekeeping Institute in 2021 which should give additional confidence for those looking to buy.
One of the many problems that people often report with comfort layers like memory foam is that they find themselves getting too hot, in part, due to foams heat retention, many mattress manufacturers try to offset this with cooling fabrics as a outer layer, but this mattress uses gel to help with temperature regulation.
Gel comfort layers, much like memory foam, offer many of the bounce back and comfort features but with improved airflow and temperature regulation.
The product also features hypoallergenic materials while providing more than enough comfort.
From the support layer we have a hybrid pairing of both pocket springs and soft tech springs, these work together to contour to your body's every movement. while reducing roll-together.
The TheraPur ActiGel® Polar 2800 Mattress also comes with a pillow top for a further layer of comfort which works alongside the layers beneath.
Owners mostly rate it well, and the praise centres on comfort and support. One owner wrote that it's "both supportive and also cooling", another that it "helped drastically with my back support and posture". On cooling, many say they sleep cooler on it, while one owner found it "doesn’t cool or regulate temperature". The negative reviews are a small share, but they don't all say the same thing. A handful report a dip forming, anywhere from the first few weeks to two years in, and a few were met by a strong chemical smell on arrival that was slow to fade. The complaint that comes up most often is tension: owners who tried it in store found the delivered mattress firmer than they expected, "a lot firmer than in the store" as one put it. There are a number of reasons this occurs and it's one we come across frequently. Ultimately a mattress in store has been laid on and used, in some cases, for years. That's going to give a different firmness and comfort than something brand new out of the factory. The good news is that with time to soften, the mattress will fall in line with in-store customers expectations and result in a comforting sleep.
*some elements of this review and the reviews supported by customers were offered against the previous model known as the Therapur ActiGel Plus Rejuvenate 2200 Mattress. The TheraPur ActiGel® Polar 2800 Mattress is an upgraded model that takes everything that was great about the response and added more springs for enhanced support and better body contouring.
