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.

I bought this mattress 2 months ago and have been having the best sleep since purchasing it! It came rolled up and was easy to set up. I ended up using it about 2-3 hours after and it was great.

A Testament to Quality and Comfort

RGM2 2/17/2024

Having been a loyal Serta user for over two decades, my expectations for the Serta Mattress-in-a-Box (Queen / Medium Firm) were naturally high. I am delighted to report that this mattress not only met but exceeded those expectations, reaffirming my trust in Serta's commitment to quality and comfort.

Best Mattress EVER!!!

Kymbo 11/29/2023

I bought this mattress back in April after healing from a back injury. Based on extensive research I decided to try this Medium Firm mattress. My parents come over to visit every week for Sunday dinner and always end up taking a long nap on my bed. They are obsessed. As am I. It has been wonderful for my back pain. It's sturdy but not too firm, it doesn't sink in too much, contours to my body. My grandparents enlisted me to purchase this exact same mattress for them in a King size. Even when my nieces and nephews visit, they make a beeline for my bed. This has been the best decision for my body, peace of mind and relaxation. I work on my feet for long periods of time and nothing is better than coming home to this mattress. It is phenomenal I couldn't recommend it more.

New purchase - limited use

Kenneth M 11/21/2023

I've slept on the mattress just once but woke up feeling better than the thinner, much older (15+ years?) and well used old Serta coil spring mattress I'm replacing. The 8" foam mattress was priced right, easy to setup and the first of it's type I've ever bought or slept on. So far a fan.

Pain free sleep

Beegee7411 11/19/2023

Bought this a month ago for my 70+ year old mother who had chronic hip pain in bed. She hasn't had any pain since sleeping on this mattress! I bought the same for myself about 1 year ago and still love mine! Which is why I purchased one for her. Thank you Serta!

It's a solid mattress and very comfortable for the price, the only downside for me is it's slightly too firm but nothing a mattress topper couldn't fix.

Give it Time!

sleepyqueen 8/5/2023

I bought this mattress about a month ago after I was experiencing neck and back pain from a mattress that was 10+ years old (yes. that old.). My old mattress had absolutely no support, and had a dip in the middle from being handed down from my mom, to my brother, and finally to me. So I knew I needed a mattress with more support. I got this in medium firm and the first few nights I was worried because I was waking up with stiffness so I thought maybe this mattress wasn't right for me. But I remember reading to give it a few weeks before you return it so I kept trying hoping that I would break it in. And I'm so glad I did! By the end of the first week, I was sleeping through the night, waking up feeling more rested, and no pain in the mornings!!!! It makes sense since I went from a mattress with literally no support to a mattress that was medium firm. My body just needed to adjust and now I absolutely love going to sleep at night! Getting in my bed is my favorite part of the day! So give it a few days before you decide you hate it.
