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.

Denise Mercadante 1/14/2025

I purchased this back in June come August I noticed that I am sleeping in a ditch I called serta for their 10-year warranty supposably and was told I have to call the store I purchased it from JCPenney their policy is they charge you $95 restocking fee and I have to purchase a new mattress so technically I'm buying two serta is telling me that the tenure warranty only is valid if the store that I purchase it is not around anymore which to me it's bull you don't stand behind your products and now 7 months later I have to purchase another mattress which I am not buying serta ever again unless they rectify this problem I'm having
