Pull all corners of the cover down over your foundation so that the cover is tightly wrapped around it like shown on the picture.

Start by placing the Firm base layer on the cover. Make sure that the rubber layer meets each corner of the covering and lines up with the foundation.

You may then place the middle layer right on top of the base layer. This layer will be Medium and can be swapped with your base layer for a firmer feel.

Now, pull the top of the cover tightly over the mattress. Start zipping each side of the bed while pulling down on the top of the cover to relieve stress on the zipper. The two zippers should meet at the head of the bed.
