Measure the inside of your bed, enter your measurements, and we'll help you find the closest Sleepfresh standard mattress size.
VIEW STANDARD SIZES →How to Measure Your Bed
Before choosing a mattress, measure the empty space inside your bed where the mattress actually sits.
Measure the Length
Measure from the inside edge at the head of the bed to the inside edge at the foot of the bed.
Measure the Width
Measure from one inside edge of the bed to the other inside edge.
Enter Your Measurement
Enter the length and width below. We will show you the matching Sleepfresh standard size.
Measure the bed space where the mattress sits — not the outside wooden frame.
