I had my first nights sleep on the new mattress and am very pleased. Even though my prior mattress had a deeper depth, I didn't sleep well on it.

I was initially skeptical of purchasing a Serta mattress in a box, but internet reviews seemed to indicate a quality product. The unpacking process was straightforward, and the product expanded within a few minutes. The first night was amazing compared to our old mattress. I was happy that the cool-feel cover retained just the right amount of heat. I would recommend this product.

Serta has the Stay listed as right between soft and firm on their scale but I'd say it leans towards the softer side, it's the type of mattress where you instantly sink and it molds to your body but it still feels very supportive through the night. I feel like mattresses are definitely personal preference, what's too hard or too soft for one person might be perfect for another but for me this was just about perfect. It's soft yet supportive and I don't have any of hip pain and leg numbness I experience with firm mattresses. Other than comfort, there were two things that stood out about the Stay to me, the first being the 4 layers of foam. The top layers give it that cushy sink in softness and the lower layers keep it supportive. If you press down hard enough especially at the edges you can feel the change in firmness. The second was the cover, it's soft and cottony and here's the big plus, it unzips all the way around (there's about an inch that does not unzip). I haven't tried it yet but it seems like it will remove completely for washing and underneath the mattress is covered with a cottony blue fabric. I have a 3-year-old and accidents happen so I'm probably overly excited that it seems to be removable and washable. It's a simple thing but it's a game changer and I can't believe all mattresses aren't made this way! Set up is fast and easy. The king box is roughly 21"x21"x46" and shipping weight showed 127 lbs, small enough to fit easily in a trunk and while heavy I was able to drag it in and set it up alone. Definitely get it on the platform or box spring before opening. It expands quickly and will be the full 12" within minutes. There is a minimal smell from the memory foam which I expected, it dissipates pretty quickly but I did open a window for a few hours to help air it out.

I can't say enough good things about this bed!!! I admit I was skeptical at getting a mattress that was delivered in a box, but I am so glad that I did get it! It is hands down the most comfortable mattress I have had. It is so nice not having to worry about springs or creaks when you are moving around. The mattress is great for all types of sleepers as well. I love to sleep on my back, but I can never seem to get comfortable in doing so,. This bed lets me sleep on my back and I wake without any back pain. The mattress conforms to all my curves and hugs everything just right. I also can move around without feeling like I am disturbing my partner and he sleeps just as well as I do as a side sleeper. I would definitely recommend this mattress and will be purchasing another one in the future.

I decided to take longer on my review because we have a mattress topper and I wanted to try this mattress without the topper in order to get a true experience. We have been nothing but impressed with this mattress! We have slept better than we have in YEARS and we don’t roll into each other anymore! The ventilated Copper Memory Foam is beyond comfortable and the Swirl Gel Memory Foam provides the perfect amount of support for us! It’s on the soft to medium side. The anti-microbial CoolFeel knit cover allows us to stay cool throughout the night! No more sweating or throwing the covers off because we’re hot! The fact that it comes in a box and all you have to do it take it out and let it decompress is amazing to me! I’ve never seen a bed like that! I think the thing I love most about our mattress is that my husband or I can get up and lay down anytime we want without disturbing the other! It’s fantastic to be able to sleep through him getting out of bed or laying down! Overall, we are thoroughly impressed with this product and highly recommend it to those looking for a comfortable, supportive foam mattress!

I’ve had my Serta Stay for about two weeks now and have been sleeping on it for the entire time. As far as first impressions go I am pleasantly surprised!! I like a very supportive mattress while my partner prefers a softer cradling. This mattress met both of our needs! It was soft yet supportive for my back issues and allowed my partner to sleep in his usual crazy positions in comfort. I was able to get in and out of bed in the middle of the night without waking my partner, and I fell asleep quickly upon returning to bed. There was no strong odor upon unpacking the mattress, popped up into shape very quickly, and was ready for sleeping on the same day! It’s quite heavy so naturally I would recommend assistance with unpacking. The mattress is very well made, no loose threads, and the memory foam doesn’t get too warm. Easily will last several years in my option if not longer. 10/10 would recommend!

My grandson has not been sleeping well and I realized that the mattress from his bed was 5 years old. Big Lots advertised a Serra Allerton mattress at a good price so I purchased it and brought it home. Beforehand it was taking B 20-30 minutes to fall asleep! Now I can hear him snoring after 10! Thank you Serra for bringing us rest. Serra is the best!

I did not have good luck with this mattress. We rotated like recommended and it still left ideations where we sleep. Would not recommend this mattress.

I was very skeptical about the process of a queen sized mattress and how it was going to expand, but after 24 hours we tried it and loved it. It is very comfortable and was reasonably priced. we got it at BigLots and the whole transaction was very quick and smooth once we made a final decision as to which one we liked best.

I enjoy the comfort of firm but not too firm support. I can't think of anything I don't like about this mattress. It doesn't sag like the previous mattress I had. All-in-all, a great value and comfortable improvement from previous bedding.

My experiences with mattresses have been mediocre to above average. My old mattress was an IKEA, and it was soft without being too soft. But the Serta Stay collection at Big Lots changes the game for me. Its 12-inch memory foam is so sturdy that you barely make an impression on it. Your back contours on it as nature intended without damaging the mattress. My partner can toss and turn on the mattress and I would barely feel a thing. On top of it all, the mattress was very economical and fit our budget. I would definitely recommend the Serta Stay to anyone seeking a value, comfortable mattress from a great brand.

I purchased this for my 6 year old bed. The quality and price seems nice

This mattress is really comfortable and very cool. The foam gives way after laying on it for a little time, but cooling feature is amazing. I sleep very hot usually, but with the cooling of the foam in this mattress I have been using the blankets. It is a little stiffer than we thought it would be, but after some time we have started to enjoy the stiffness of it. Great mattress and worth every penny.

The matrice cover leaked on my bed. And also bed I t has sunk in middle when the tag said it material down sink down really disappointed in both products when I payed a lot of money for it. I have no way of replacing it. Other bills to pay for.

Most Big Lots Store’s carry this mattress but, all the stores in the area were out of stock! Traveled a hour away to purchase this good quaility mattress at a great price.

This Dayton mattress is perfect for my daughter's bedroom. It is cozy, just the right softness. I purchased it at a great price compared to other mattress stores.

The Serta reputation was the primary reason I chose to look only at their mattresses when shopping for a new one.

Comfortable all around for sleep and sitting. We use it to relax and read, watch TV and sleep.

We bought the Serta Stay mattress and the Serta adjustable foundation together and couldn’t be more happier with it it’s very comfortable and it doesn’t make me hot like some memory foam mattress does we looked at the more expensive brands but I love the quality of this one so glad we went with this one.

What I like about this product is that it has several layers and is of good quality. The comparison of the memory foam to a regular spring mattress is 100 times better. My sleep as improved so much. My back feels better, I sleep better and can sleep on my side. I did not know that Serta had this quality of a memory foam mattress until i walked into Big Lots. I laid on it. Read the information and the layers it had was what I was looking for. I would recommend this mattress.
