Is a twin XL size right for me?
A twin XL mattress is the same width as its standard twin size counterpart but offers 5 extra inches in length.
The twin XL mattress is an ideal option for taller sleepers such as growing children or college students.
As a general rule of thumb, your bedroom space should be at least 8 x 10 feet in order to be comfortable.

Frequently asked questions
A twin XL size mattress is 80" long and 38" wide.
The twin XL size mattress is great for single sleepers looking for extra legroom, often those who are more than six feet tall. This includes teens, college students, and adults who may lack bedroom space for a wider mattress size.
The twin XL is the same width as a standard twin but shares the same length as a queen or king. This makes it a perfect space-saving solution for narrow rooms that still need to accommodate adults or tall teenagers. We recommend a minimum room size of 7 x 10 feet to allow for comfortable movement around the bed.
You will need a twin XL bed frame for a twin XL mattress. A twin mattress bed frame is not compatible with a twin XL mattress because twin and twin XL are different bed sizes. If you have a resizable bed frame that features an adjustable length and width, you can use this frame for your twin XL bed. You can also put two twin XL mattresses together and they will fit on a king size bed frame or a split king bed frame.
Purple mattresses are not intended for use with a box spring. Our mattresses are best supported by an adjustable base or platform frame, like our Upholstered Bed Frame and Metal Platform. 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.
When you put two twin XL beds together, they have the same dimensions as a king size mattress (king size bed dimensions are 76” x 80"). Two twin XL beds put together are normally referred to as a split king. Split king mattresses are commonly used on split king adjustable bed frames. This allows each partner to adjust their side of the bed to their liking.
Purple’s twin XL mattresses cost between $849 - $7,499, depending on model choice. Thanks to Purple’s 100-night risk-free sleep trial, there’s no stress if the mattress isn’t a match. Just contact Purple’s customer service team within the first 100 days for a refund.
A twin XL mattress and a twin mattress have the same width, but the twin XL is 5” longer than the standard twin size. Due to the added length, a twin XL mattress does require a different size bed frame and bedding.
