Memory foam works best with natural body heat. Using an electric blanket with a memory foam mattress will affect how the material feels and performs. So you should avoid using the two together where possible.
A mattress protector is a removable cover that helps keep your mattress clean, hygienic, and in good condition.
It creates an extra barrier protecting the mattress from stains, spillages, and even bed bugs.
A mattress topper is an extra layer of cushioning that can help improve the comfort of your mattress. It sits on top of your mattress, beneath your sheets and can make your mattress feel softer or firmer.
