The Tristar BW-4752 electric thermal blanket ensures a pleasantly pre-heated bed and increases sleeping comfort, especially in the cold season. The underblanket is placed directly on the mattress and heats the bed evenly, so that you can lie down in a comfortably warm sleeping environment. With its generous size, it is ideal for double beds and can be used by two people. :contentReference[oaicite:0]{index=0} Two separately controllable heating zones allow both sides of the bed to set the desired temperature individually. The heated blanket has several heating levels and thus offers a comfortable temperature for different needs. The soft polyester material ensures a high level of comfort, while the integrated superheating mechanism prevents the comfort of the mattress.
