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.
Then place the second Firm layer beside it, gently pull and push the material so that it lines up on all sides.
You may then place the middle layer(s) right on top of the base layer. This layer will be Firm, Medium or Soft and can be swapped with your base layer for a firmer feel.
The last piece will be the top soft rubber top layer, this is not split. Always make sure that this piece is well aligned and nicely squared with the other pieces.
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.
