Mattress Size Chart: At-a-Glance

Pro tip: Always measure your room first. Leave at least 24–30 inches of walking space around the bed for a comfortable layout.

King vs. Queen: Which One Is Right For You?

Choosing between a king and queen mattress is one of the most common bed size decisions. Both are popular options for primary bedrooms, but the best mattress size depends on your room dimensions, sleep style, and whether you share the bed.

Choose a Queen Mattress If:

• Your bedroom is 12' x 12' or smaller
• You want flexibility for nightstands, dressers, or bedroom seating
• You're a couple who doesn't mind sleeping a bit closer
• You're balancing comfort with value

A queen mattress is often the most popular choice thanks to its versatility and wide selection of styles.

Choose a King Mattress If:

• You have a spacious primary bedroom
• You or your partner toss and turn
• Kids or pets share the bed
• You want hotel-level sleep space at home

• Adjustable bases provide customizable comfort

Don't Forget the Finishing Touches  

Protect your investment and extend the life of your mattress with the right accessories:

• Mattress protectors for spills, allergens, and general protection 
  
  

Pro Tip: Mattress protectors are also a requirement for comfort returns and warranty coverage.



• Breathable or cooling sheets sized specifically for your mattress depth
• Pillows tailored to your sleep position

Many mattress brands—like Tempur-Pedic, Purple, Casper, and Beautyrest Black—have their own line of mattress accessories so you can get a complete sleep system that is designed to give you a consistent experience.
