## Questions & Answers

**Q: Is there a trial period? Will Amazon pick up mattress if you don’t like it?**
A: Buy it from Costco instead. It's $80 cheaper including shipping and there is no trial period. You can return it ANY TIME for a FULL REFUND. They will send a freight service to pick it up AT NO CHARGE!

**Q: Is this mattress heavier when fully expanded**
A: The weight is the same before and after it has expanded.  It is very heavy. It is much more difficult to move it when it is expanded.

**Q: Does this mattress require a foindation or can it go on top of slats?**
A: Hello, Thank you for your inquiry. Your mattress requires a firm, solid surface (like a Sealy Foundation) or power base (like an Ease 2.0 base) that is structurally capable of supporting it. While Sealy mattresses can be used directly on the ground we do not recommend slatted support or traditional box springs as both of these do not provide the required support.  Please contact our Customer Service Representatives at (800) 697-3259 with any further questions.

**Q: How many coils (please provide an actual number) does this mattress have? Thanks**
A: Hello R.M., Thank you for your inquiry. The Queen Size has 968 coils encased inside of it. Please contact our Customer Service Representatives at (800) 697-3259 with any further questions.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very comfortable
*by R***I on June 10, 2025*

Super comfortable. I've been using this mattress for about two years and I've noticed no significant wear or breakdown.

### ⭐⭐⭐⭐⭐ Actually a good mattress from Amazon? Nope, a great one! Made in USA
*by M***W on July 21, 2023*

Was trapped undecided between this and some offerings at Costco. Honestly I don't make that much so even what would normally be thought of as somewhat inexpensive or affordable for a mattress took no small amount of savings. I wanted to get it right and my gosh was it agonizing to choose. Such an unreasonable and almost senseless gamble to buy a mattress online without ever testing it in person especially a mattress in a box, typically mass made in china and drop shipped by some third party company that charges multiple times it's actual cost, you know what I mean.Now I typically take careful consideration of negative reviews especially in issues that are consistently reported and for that reason, despite all the stellar reviews on other websites, every mattress within budget had a repetition of negative issues. This mattress seemed the most consistently well reviewed across several websites, and all things considered I was willing to go quite a bit more over budget for something so vital as a mattress.With all that out the way I'll say it now, this mattress has been so much better than I could have hoped for. It's soft, very soft, mostly dues to the extra thick topper but with the support of an actual coil frame. I personally cannot stand foam mattresses, and all the nice spring or hybrid mattresses where just too much. Then again my main concern with hybrid mattresses are the hazardous materials used in manufacturing. They check all the boxes for flame resistance and what have you but the toxicity was not something I wanted to risk. Imagine having to de-gas your mattress and even then the materials aren't going to decide to not be carcinogenic just because you sleep with them. It's isn't verifiable what these offshore manufacturers are using but this mattress is made in the US.I did spent quite a bit of time researching into it's safety and manufacturing and since this is too much already for a simple review, I'll end this by saying: this mattress is sooo comfortable, well made, and safely made. (Just don't jump on it like a fool and complain the support gives out or pile drive the thing with all 400 something pounds of yourself after a long day and then go on amazon to complain when the knit cover starts to inevitably tear. It's still a product that needs to be taken care of just as everything else).

### ⭐⭐⭐⭐⭐ Very comfortable, high quality, recommended
*by S***N on July 27, 2022*

I'll admit to having been skeptical about purchasing a mattress in a box. The reviews for the most popular ones were all over the place, adding to my doubt. When I bumped up the price range I was looking for and decided to focus on established brands, this Sealy stood out from the rest. I took the plunge and ordered it.It arrived 4 days earlier than estimated. I set it up early the next morning before going to work to give it time to expand. Set up was simple, the hardest part was getting a 60 pound box up the stairs and my old mattress out of the way. As I got to the end of the shrink wrap, the mattress began uncoiling, slowly enough that I had enough time to position it atop my existing box spring.There was no odor, as some reviews on some products mention. It assumed full shape pretty quickly and was ready for sheets, etc. when I got home from work. I slept on it that night.It's very comfortable, I toss and turn a whole lot less than I used to do, my sleep quality is definitely improved! The memory foam conforms to me while being neither too soft nor too firm. The springs underneath provide good support for the whole thing. I'm very pleased with it.I used my existing bed frame and box spring, which went against the recommendations but I have three metal cross bars on the frame each with a support in the middle and they all attach to the wooden side rails that slot into the head and foot boards with metal supports. If you have a sturdy bed frame, you'll be OK. You will need a box spring if you do not have a platform bed frame. With all that, the mattress does weigh 60 pounds so make sure you can accomodate that weight.Final comment, sitting on the edge of this mattress is no different from doing so on a regular mattress, it's plenty firm enough, the memory foam and coil springs support my 250 pounds just fine.
