When It Comes to Mattresses, Size Matters

Picking a mattress size is the first step toward better sleep. There are many factors that you should keep in mind when picking the mattress that’s right for you: your space, your sleeping arrangements, and your habits.

Is your home a little space challenged? Do you love to spread out? Does your partner? Does your dog share the bed? Let’s figure out which size is best for you!

Here’s a quick look at mattress sizes in inches:

  • Twin: 39” x 75”
  • Full: 54” x 75”
  • Queen: 60” x 80”
  • King: 75” x 80”
  • California King: 72” x 84”

Twin & Full

If your space is small or you’re shopping for a child, check out a twin (or twin XL) or a full mattress. While these sizes may not provide the most room to spread out, there’s still plenty of comfort to be had! These bed sizes are ideal for bunk beds, day beds, loft spaces, futons (full), or guest rooms.

Queen

Need more room for yourself, or for you and your partner? Give a queen mattress a try for more room and more comfortable sleep. Be sure to measure out your bedroom or sleep space before getting a bed larger than a full.

King

If that’s still not enough, check out a king mattress. These mattresses are typically more than enough room for you, your partner, and maybe even a pet or two.

California King

Want to amp it up? You could even take things up to the next level with a California king. These mattresses are some of the largest you can find and can provide enough room for those nights the kids have nightmares and need a safe place to get back to sleep.

All our mattress sizes come in different styles, from innerspring to memory foam and hybrid, latex to mattress in a box. No matter what you’re looking for or the size of your family, we have the mattress sizes that can cater to your needs.
