Most mattresses on the market have standard sizes, so they can fit into most types of bed frames, foundations, and other support systems. Leesa is no exception.

Here is a quick look at the dimensions of common Leesa mattress sizes.
- Twin: 38×74.5″
- Twin XL: 38×79.5″
- Full: 52.5×74.5″
- Queen: 59.5×79.5″
- King: 75.5×79.5″
- Cal. King: 71.5×83.5″
The full-size version is slightly wider and shorter than the average, but it should still fit most types of support systems.
