How to Properly Measure the Length, Width and Depth of your Mattress and Box Spring

Use a tape measure to determine the size of your mattress and box spring in inches.

1. Measure the Height: Measure, in inches, from the bottom, where it rests on the box spring, to the top of the mattress including any pillow top. If necessary, repeat for box spring.
2. Measure the Length: Measure the length, in inches, from the head of the mattress to the foot of the mattress. If necessary, repeat for box spring.
3. Measure the Width: Measure the width, in inches, of the mattress from side to side.  If necessary, repeat for box spring.

Note: It is important to properly measure your mattress and box spring frame before purchasing an encasement. We do not accept exchanges or returns on opened packages due to hygiene and bed bug concerns.

Do You Have A "Split" Box Spring?

Before ordering your box spring encasement, make sure your mattress has a single or a "split" box spring set. If you have a King or Queen mattress, use the table below to order the proper box spring encasement for your box spring configuration.
