What mattress size should I look for?

The answer to this question depends on many factors, such as the size of your bedroom and the type of sleeping position you prefer. If you sleep alone in a small room, a twin or single mattress may be fine. However, if you share your bed with a partner or have a larger bedroom, you may want to consider a queen or king-size mattress.

There are also extra-large mattresses, called “California Kings” (72″ x 84″), which are great for tall people or those who need plenty of room to move around at night or sleep with their kids or pets, so there’s room for everyone. Whatever mattress size you choose, make sure it’s comfortable and provides the support you need for a restful night’s sleep.
