Thank you for sharing the information. It will be very helpful to many people. When I was choosing a mattress to buy, I could not decide which one to choose for a long time, as there are a considerable number of them on the market and I do not know what to buy. A good mattress is very important for good sleep. And I searched the Internet for instructions on which mattress is worth buying. I read an article on https://bedselection.co.uk/how-to-choose-your-perfect-mattress/. I think you should also read it, maybe find some useful information.
