Frequently asked questions
Before you buy, it’s important to understand the difference between a twin vs. twin XL bed frame to ensure your new bed frame fits both your mattress and your room:
Standard twin bed frame: Measuring 38” x 75”, the standard twin size mattress is a compact and space-efficient option that works well for children, guest rooms, and single sleepers under six feet tall. Twin bed frames are typically more affordable and make it easier to find compatible sheets, bed frames, and accessories.
Twin XL bed frame: Measuring 38” x 80”, the twin XL size mattress offers the same width as a standard twin with an additional five inches of length for extra legroom. Twin XL bed frames are ideal for taller sleepers, fast-growing children, and college dorm rooms where maximizing comfort in smaller spaces matters.
Twin XL size bed frames typically range from 37” - 43” wide and 79” - 85” long.
In general, bed frames are 2” to 5" wider and longer than their corresponding mattress sizes. However, some lower profile styles, like platform bed frames, may be closer to the exact dimensions of the mattress.
We recommend purchasing a bed frame for your Purple mattress right here at Purple. We offer a wide range of ergonomic bed frames, foundations, and adjustable bases engineered for sturdy, creak-free support. If you’d prefer to experience them in person — find our assortment of bed frames at the closest retailer near you.
Purple twin XL size bed frames range between $349 for the Metal Platform and $599 - $1,595 for an adjustable base. Please note that prices are subject to change.
A twin XL mattress is the same width as a twin size mattress, but it’s 5" longer. Accordingly, a twin XL bed frame is specifically made for the longer mattress size and is typically about 5” longer than a twin bed frame. As such, twin XL size mattresses are not compatible with twin size bed frames.
A twin XL mattress is the same width as a twin size mattress, but it’s 5" longer. Accordingly, a twin XL bed frame is specifically made for the longer mattress size and is typically about 5" longer than a twin bed frame. As such, twin mattresses are not compatible with twin XL bed frames.
Note that a twin XL mattress is exactly half the size of a king mattress, so two twin XL mattresses can be combined to make a split king bed.
Twin XL mattresses are commonly used in college dorms, while twin mattresses are primarily used for children. A twin XL is a good option for taller teens and adults who can use an extra 5" in mattress length.
No, mattresses and bed frames are sold separately, though we recommend checking out our sale page, as we often offer a discount when purchasing both.
