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.

New Harbor Creek Mattress feels so good and supportive. Definitely an upgrade from my old Casper mattress. Doesn't sink in and has helped alleviate the pain I was experiencing. If you're interested in a mattress that's firm and at a reasonable price this is for you

Melanie H 4/29/2026

My husband loves a firm mattress as he is a stomach sleeper. This mattress is very firm and supportive. Personally, I'd like to add a 2" memory foam topper as it's almost too firm for me. But he loves it!

Harbor Creek

Angela E 4/4/2026

I purchased my Habor Creek firm mattress from Sam's today. Of course, I was unable to test the feel of the mattress in the store but as soon as I got it home, I laid on it and was pleasantly surprised. I was afraid it was going to be too firm but it wasn't. It gave just the right amount of give. So for, so good and I recommend.
