Customer Reviews
Good mattress, smooth delivery
I ordered a King Serta mattress from Mattress Firm again, just like a few years ago. The delivery was right on schedule, and they even took away my old one. It's nice knowing what to expect, and they delivered. Good experience overall, consistent with my last purchase.
New pillows are great!
I just got two cooling pillows and a set of sheets, and they're amazing! My sleep has already gotten so much better. I'm definitely going to shop here again for more bedding accessories. You should too!
New memory foam mattress for guest room
I needed a new full-size memory foam mattress for my guest room, and Mattress Firm had a good selection. Ordering online was pretty straightforward; the website was easy enough to navigate. I had a quick question about delivery times, so I used their chat feature, and the agent was helpful and answered everything quickly. The mattress arrived two days earlier than the tracking said, which was a pleasant surprise. The delivery crew called ahead and were polite and efficient getting it set up. The mattress itself seems like good quality for the price I paid, and my first guest said it was quite comfortable. They also offered to take the old mattress, which saved me a hassle. Happy with this purchase and the whole process.

Hey, wondering if anyone knows if Mattress Firm does free old mattress removal when they deliver the new one? My old one is huge and I don't wanna deal with it.
Thinking of getting a new bed during the Memorial Day sale. Does Mattress Firm usually have good deals then, like with adjustable bases?
Anyone know how Mattress Firm compares to Saatva? Looking for a new queen but not sure which one has better quality for the price.
How's the return process with Mattress Firm? I'm worried about buying a mattress online and hating it.
Can you stack promo codes at Mattress Firm? I have a military discount and also saw a 10% off for signing up for emails.
