Are memory foam mattresses / overlays (toppers) hot to sleep on and will they make me sweat?
The open cell structure of MF, compared to normal foam products, greatly reduces the creation of so-called hotspots that can make you perspire excessively during the night. However, a MF mattress or overlay with a thickness over 7 cm might also prove to deep and again could lead to excessive perspiring. This is one of the reasons why we neither sell nor recommend the use of MF that is more than 7 cm in depth. In any event, all our memory foam mattresses / overlays (toppers) come complete with our unique ExtraAirflow cotton covers that promote extra air circulation between you and your memory foam mattress/overlay (without effecting the benefits of the memory foam), thus further preventing any potential hotspots.
