Our mattress kits can be assembled in a few short minutes. Most people find it easier to have a second person to help lay the foam across your foundation. The 4 steps for assembly: 1. Place the bottom of cover on top of your base. 2. Place the support layers of on top of each with the firmest on bottom. Take special care to position them straight. 3. Place your comfort layers on top of the support layers once again taking care that all the layers are straight. 4. Stretch the cover over the kit and zip around the perimeter.
