Twin size mattresses are the smallest, and coziest, mattress size on the market, but we still manage to pack a lot of high-quality comfort and support into this 38” x 75” sleep space. Twin size mattresses tend to be more affordable due to their smaller size, but they can be a practical option for most sleep needs.
Not to be mistaken for twin XL mattresses, standard twin size mattresses are 38 inches wide by 75 inches long. Twin XL mattresses measure 5 inches longer at 80 inches in length.
Kids & Teens
Ideal for individuals who do not require much sleeping space, twin beds are just the right size for growing children, teens & bunk beds.
Small Bedrooms
As the smallest mattress size, twin mattresses are perfect for smaller rooms or rooms with odd configurations.
Low Budget Upgrades
Twin mattresses are one of the most affordable sizes on the market, making them practical for high-quality, lower-budget bedroom upgrades.
