When purchasing a new mattress, you should consider replacing your foundation as well. It may appear that your new mattress is sagging when the problem could be with the old foundation providing inadequate support.
To ensure the best performance for your mattress, we recommend the use of an appropriate Sealy foundation which has been designed to work in conjunction with your mattress to ensure the correct level of support.
When used on a platform or slat bases, your mattress will not last as long as it would on its companion sprung foundation.
Turn the foundation/base of the mattress upside down and insert pintle into hole and turn clockwise, repeat for all legs.
Tighten by hand until legs are firmly in place.
Turn the foundation back over and re-tighten legs as tightly as possible by hand, check and re-tighten where necessary every three months.
