Is a Full Size Right For Me?
The full size mattress is the same length as a twin but is 16 inches wider.
The full is an ideal option for single sleepers wanting more space to move around in bed.
As a general rule of thumb, your bedroom space should be at least 9 x 9.5 feet to provide plenty of space.

Frequently Asked Questions
A full size mattress is 75" long and 54" wide.
Full size mattresses are generally recommended for a single adult or teen sleeper with bedroom space to accommodate a larger mattress than a twin or twin XL.
Yes, but it’s considered snug. A full size mattress is 54" wide, which leaves each sleeper just over 2 feet of wiggle room. That’s not much, especially for larger sleepers. For that reason, the queen mattress has become the new standard for couples. Depending on your comfort with a tighter fit and your available bedroom space, a full might work for you and your partner.
Purple mattresses are the best mattresses for couples. Purple’s signature GelFlex Grid technology minimizes motion transfer and adapts to every body type + sleep position, which makes it great for couples with unique mattress preferences.
No, a full size mattress is not the same as a queen mattress. The queen bed size is 5" longer and 6" wider than a full bed. For this reason, the queen bed is a popular mattress for couples and a full size bed is generally recommended for a single adult or teen sleeper.
Full mattress: 54” wide x 75" long
Queen mattress: 60” wide x 80” long

Meanwhile, our Flat Foundation adds proper support to bed frames that lack supportive slats. All of our bed frames and foundations are made specifically to support Purple mattresses, so you know they’ll be a perfect fit and protect your investment for years to come.
