Mattress Buying Guide & FAQ

Standard mattress sizes

  • Twin: 38" x 75"
  • Twin XL: 38" x 80"
  • Full (Double): 54" x 75"
  • Queen: 60" x 80"
  • King: 78" x 80"

Mattress sizing can vary very slightly based on how the mattress is built, so these sizes are approximate.

Do I need a box spring or foundation?

That depends. Every mattress needs to be supported properly in order for it to feel right and preserve the integrity of the construction. Using inadequate support will most likely destroy your mattress in a relatively short time.

The most common ways of supporting a mattress are:

  • Box spring (also called a foundation): sits either on a standard metal frame or inside a wood or fabric bed. A box spring and a simple frame are usually the most affordable way to create proper support for your mattress. We recommend a frame with center support for any full size mattress or larger.
  • Platform bed: has either a solid board or slats with very small gaps between them. These beds can be tricky, as many of the less expensive ones don't hold up well and will lead to a saggy mattress.
  • Adjustable base: an electric base that adjusts at the head and foot. Some offer extra features like massage and USB ports. They can usually sit inside most wood or fabric bed frames as well.

Do I need a mattress protector?

Absolutely! Most mattress manufacturers require the use of a protector to keep the warranty valid. This is because mattresses absorb moisture and dead skin cells, which leads to the breakdown of the foams used in the mattress.

When should I replace my mattress?

That depends on a few factors. The main one is if you are no longer sleeping comfortably. If you notice any sagging or tears, it is time to shop for a new mattress as well.

In general, the better mattresses from reputable brands will last at least 10 years, and usually longer!

Memory foam, innerspring or hybrid?

The mattress type really boils down to what you feel more comfortable on. All types can feel great or lousy.

Firm or plush?

We find that side sleepers generally prefer medium or plush, and back sleepers prefer firm. There are many exceptions to this, though.

Do more expensive mattresses last longer?

Not necessarily. Assuming you are purchasing a reputable brand, the more expensive models will usually have more sophisticated materials that elevate the comfort and temperature regulation of the mattress.

Cheaper mattresses can last a while, but they will usually be less comfy and supportive.
