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.

More firm than expected

Kelly D 1/29/2026

It probably needs more time to break in, but the mattress feels significantly more firm that the one we tried on display. I understand there is a break in period, but I am needing to put a mattress topper on just to be able to sleep on this. I reverted back to my old bed for a short time to recover from the first 10 days. Going to try again soon. I've also been walking on it and having my kids jump on it to try to soften it up. In the store, my body sunk into it really well. At home, it's more stiff, and I can't get comfortable.
