We have a simba mattress which although very comfortable, makes us very hot. I had read about wool filled mattress toppers helping to regulate body temperature and found baavet.co.uk. We decided to try the baavet as well. They work a treat, we are no longer waking in the night feeling hot and sweaty,. The duvet feels luxurious and has a nice weight and I think, a very comforting smell. Very pleased with our purchase, like others have said, we don’t want to get out of bed. Have been recommending to everyone we know.
