Mattress Safe Stretch Knit Box Spring Encasement

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.

Properly Installing Your Mattress and Box Spring:

Installation Only Takes a Few Easy Steps:

• Installation should be done with a partner - Installing alone can stress the zipper end stops on each side.
• Starting at the head of the bed, unzip the encasement and gather the fabric to locate the bottom two end corners.
• Together with a partner, lift each side of the end of the mattress and rest it on your knee.
• Align and apply the end corners first to the end of the mattress on each side.
• Carefully slide the encasement, inch by inch, down the length of the mattress, avoiding stress on the zipper end stop.
• Align the corners of the cover with the corners of the mattress.
• Zip the cover all around the mattress and lock the “Zipper with the Hook”.
• Repeat these instructions for the box spring encasement (or you may lift the box spring to stand on its end and the encasement may be pulled down the length of the box spring).

Properly Measuring Your Mattress

It is important to properly measure your mattress and box spring. Mattress encasements are not returnable. Please use the following guidelines to measure correctly.

Determine the Depth of the Mattress and Box Spring

• Using a tape measure, determine the height, in inches, of the mattress.
• To measure the height of the mattress, measure from the bottom, where it rests on the box spring, to the top of the mattress including any pillow top.
• Repeat for the box spring.

Determine the Size of the Mattress and Box Spring

Determine the length

• Measure the length, in inches, from the head of the mattress to the foot of the mattress.
• Repeat for the box spring.

Determine the width

• Measure the width, in inches, of the mattress from side to side.
• Repeat for the box spring.

King Box Spring come in either 1 complete piece or 2 long twin pieces. Please check your box spring before ordering the encasement.
