Hello, who can tell you what kind of design beds are there?
Hello to all. I would like to point out that in terms of design, Sleep Number smart beds are similar to any other mattress. You can read the Sleep Number reviews here https://sleep-number.pissedconsumer.com/customer-service.html to make sure each has an upper "comfort" section made up of layers of foam and a lower "support" section. In Sleep Number mattresses, instead of foam or springs in the lower support section of conventional mattresses, this support section consists of an adjustable air chamber.
