Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.
Extended warranties are usually very inexpensive and can save you thousands in the future.
It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.
Mattresses
can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new
bedding
should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Comfortable mattress, but one area appears to be not as firm as other sections. I have added a 3/4 plywood to help, but it only improved a little.

This mattress is perfect for my chronic joint pain. It's just firm enough to be supportive and soft enough that it doesn't feel like I'm sleeping on an immovable plank.
