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.

Love my new mattress!

Susan J 6/12/2026

I was excited to see that my Sam's Club was running a deal on the Serta Morning Slumber Traditional Medium PLUS two bunkie boards, all under $600.00. I have just moved and previously was sleeping on an air mattress until I found a mattress. It was delivered today and I'm anxiously waiting for bed. Quality mattress that will last me for several years!
