Is a Twin Size Mattress Right For Me?

The twin is the smallest of all mattress sizes, outside of crib mattresses, which means it’s often ideal for smaller audiences.

A twin bed can work for you if you’re working with any bedroom space that’s at least 7 x 10 feet.

If your bedroom is atleast 7 x 10 feet, then a twin can work for you. Having a smaller mattress will provide extra room for additional furniture

How Big Is a Twin Size Mattress?

A twin size mattress measures 38 X 75 inches. These twin bed dimensions are standard throughout the industry. Be careful not to confuse a standard twin mattress size with a twin XL mattress size. These two mattresses are very similar, and the difference between them is important to know.

  • Twin Mattress: 38 X 75 inches
  • Twin XL Mattress: 38 X 80 inches

The twin mattress size is the smallest mattress size offered by most mattress companies. The only smaller size is a crib mattress. The next size larger than a twin and twin XL is a full mattress (also called a double bed). A full mattress is a popular choice for single adult sleepers, while twin mattresses are a good fit for children.

Frequently asked questions.

Who should sleep on a twin size mattress?

A standard twin bed size is ideal for a child’s bedroom or an adult with limited bedroom space. A twin XL mattress works great for taller teens and adults who need the 5 extra inches of legroom. We’d only recommend a twin mattress for an adult if a lack of space makes it the only option. If you want to maximize space in your bedroom or small apartment, sometimes a twin mattress is the best choice. Otherwise, adults will be a lot more comfortable on a full-size mattress or larger.

The twin-sized Purple® Mattress is made with the same premium materials as its larger models, featuring a SoftFlex cover and the luxurious comfort and support of the Purple Grid™.

What is the best twin size mattress?

Choosing the best twin size mattress for you will depend on how you sleep and what type of mattress you like. For example, side sleepers are likely to enjoy a plush mattress while stomach sleepers may prefer a firm mattress. 

Some mattress types include: 
Memory foam mattress
Innerspring mattress
Latex mattress
Purple® Mattress
Hybrid mattress (a combination of innerspring and another mattress type)

Can two people sleep in a twin bed?

Probably not. That would be a pretty tight fit. But if both sleepers are petite and don’t mind cuddling all night long, it could be possible. Twin beds are made for single sleepers—usually children. If you’re a single adult with the bedroom space to spare, we’d recommend going with a full or queen mattress over a twin.

If you’re looking for a mattress for couples, the most popular choice is a queen mattress. At 60 X 80 inches, there’s plenty of space for two. The king mattress and California king are also popular choices for larger bedrooms.

The Purple® Mattress is an especially smart choice for couples thanks to its universal firmness. Many couples can’t agree on what type of mattress they want (firm, soft, or something in between). Purple’s one-of-a-kind comfort layer, the Purple Grid™, responds to each body with custom contouring support regardless of the body type or sleep position. Couples can enjoy the same level of restful, rejuvenating sleep no matter even with different sleeping preferences.

What is the difference between a twin bed and a single bed?

A twin bed and a single bed are the same. They are two different terms to describe mattresses that measure 38 x 75 inches. It might be a bit confusing that a “twin” bed is intended for use by a single person. But the reason we call it a twin is that these single beds are often used in pairs in bedrooms that sleep two people (usually children).

Does a twin mattress need a box spring?

Purple® Mattresses are not intended for use with a box spring. A Purple twin mattress is best supported by a Purple platform bed frame. These bed frames are made specifically to support Purple® Mattresses, so you know they’ll be a perfect fit and protect your investment for years to come. 

Twin Size Platform Bed: Affordable, solid, supportive—it’s all you need.
Twin Size Foundation: Stylish upholstered mattress foundation.
