About Our Full Size Mattresses

Want more sleeping space than a twin bed offers, but you don’t have the room for a queen or king bed? A full mattress is the ideal middle ground. It feels luxurious without overwhelming smaller bedrooms. If you decide it’s right for you, shop the full mattress sales at Sit ‘n Sleep for the best selection at affordable prices. 

What Size is a Full Size Mattress

A full bed mattress, which is sometimes called a double mattress, is typically 54 inches wide and 75 inches long. Compare that to a twin mattress, which is the same length but only 38 inches wide, and you’ll see that you get a lot more sleep space with full size mattresses. If you have any reason to upgrade your twin, whether it’s a child outgrowing their bed or you’re moving to a new bedroom with more space, the full mattress is the next logical step.

Benefits of a Full Size Mattress

Full mattresses offer a lot of flexibility, making them an ideal choice for your home. Here are some of the reasons it’s worth looking into a full size mattress:

  • Space-Saving. Full-size mattressesare smaller than king and queen beds, so they're a good option for more compact spaces like guest rooms and small bedrooms, as well as dorm rooms and studio apartments.
  • Cost-Effectiveness. A mattress that’s full size is typically more affordable than larger queens and kings. (And the same is usually true for full size bed frames and bedding.)
  • Comfort. Full size mattresses are wider than a twin or twin XL, which gives single sleepers more room to spread out and relax. 
  • Versatility. But full mattresses aren’t just for single sleepers! They’re also roomy enough for a couple, a parent and child, or you and your pet. 

How to Choose the Best Full Size Mattress for You

Deciding to purchase a full size mattress is the first step. The second is determining which one will give you the most comfortable sleep experience. There are many full mattresses from top brands, and you need to consider several factors to help you make the right purchase:

  • Sleeping Position. This is important because it will tell you how firm your mattress should be. If you’re a side sleeper, look for a medium to soft mattress that will cradle your hips and shoulders. If you sleep on your back or stomach, your mattress should be medium to firm. 
  • Feel. Typically, higher-quality materials result in a higher comfort level. The type of materials also matters. Coils and latex foam make a bed bouncier, while memory foam and poly foam provide cushioning pressure relief. 
  • Motion Isolation. Need a full size mattress for two? It should be engineered to reduce the transfer of movement, so you don’t feel the shift when your partner moves around or gets in and out of bed.
  • Durability. Look for a brand that clearly states what materials were used in the mattress construction. Generally, innerspring mattresses with more support coils offer the most durability.
  • Temperature. If you sleep hot, consider a mattress with cooling technology that will help you sleep more comfortably.

When you’re mattress shopping, you should also think about your body type (taller people may want a mattress that has enough length for their build, for instance), cost, the size of your bedroom, and other personal preferences. When testing mattresses, spend at least 10 minutes on each one and ask the salesperson for a pillow to get an accurate feel for what it will be like to sleep on them.
