Care
Preventative care is the best way of maintaining a great night’s sleep on your mattress. Mattress Pads protect your mattress and provide a protection plan that covers your mattress if stains occur. Vacuuming is the best way to attempt to clean a mattress yourself. Do not use any type of dry-cleaning fluid as it can damage the foam and other materials in your mattress.
