Things to Consider When Shopping for the Best King Size Mattress Under £400

Firmness Level

How do you generally prefer to sleep at night, position-wise? If you are a back or stomach sleeper, then you might want to choose a firmer mattress.

Materials and Layers

Do you want your best king size mattress under £400 size to be more supportive, or are you more concerned with the comfort level? Generally speaking, if the emphasis is placed on the springs, then the mattress will be much firmer.

Type of Foam

Polyfoam is cheaper and supportive, whereas convoluted foam is an excellent choice for heat dissipation. However, many people nowadays prefer memory foam thanks to its ability to contour around your body.

Warranty
