Nope! Expand a Bed's patent pending high density foam side supports and tensioning straps allows Expand a Bed to fit perfectly on any Twin XL mattress.

Nope! Expand a Bed can be used with any Twin XL bed frame. The patent pending high density foam side supports and tensioning straps act as a Twin XL frame extender!

Our return policy allows customers to return mattress toppers within 30 days of purchase for a full refund, provided the product is in its original condition.

On average under 3 minutes! Simply lay Expand a Bed over the existing Twin XL mattress and thread the tensioning straps around the frame and back to the connection points. Then tighten. That's it!

Full XL bed sheets work great. Even though Expand a Bed is not quite as large as a Full XL mattress, Full XL fitted sheets still fit great.
