Twin XL size beds are ideal for tall sleepers, or smaller spaces such as studio apartments.
Great for tall sleepers
For sleepers who need a little extra legroom, the long dimensions of a twin XL mattress are ideal.
Compact & comfy
For small spaces, studio apartments, or college dorm rooms, twin XL beds are a practical yet cozy choice.
Adaptable for couples
Join two twin XL mattresses together for a king size bed that works perfectly with a split base.
Every Puffy mattress has been designed with cloudlike comfort in mind. That's why our distinct, plush feel is the first thing you'll notice once you order your Puffy twin XL. Here's a closer look at what makes us so unique:
Cool Touch Quilted Cloud Cover
Our Cool Touch Quilted Cloud Cover, with its luxuriously soft quilted design, enhances the mattress’s cooling sleep surface. Woven with exclusive cooling yarns, this smooth layer promotes airflow to keep your mattress breathable and comfortable.
Cooling Cloud™
The Cooling Cloud™ Foam layer is a gel-infused foam that maximizes air circulation, dispersing heat from the body. It is also designed to cradle muscles and joints, for comfort in every sleeping position.
