This Queen mattress completely exceeded my expectations. From the very first night, I could feel the difference — it’s incredibly supportive, yet soft enough to feel like you’re sleeping on a cloud. No more tossing and turning or waking up with back pain! The quality is top-notch. It holds its shape beautifully, has no weird odors out of the box, and the materials feel premium. I also love how quiet it is — no creaking or motion transfer, which is perfect if you share the bed. Honestly, I didn’t realize how much a good mattress could impact my mood and energy levels until I switched to this one. If you’re looking for a mattress that delivers comfort, quality, and restful sleep, this is it. 100% recommend!

Very comfortable mattress! It was easy to set up, expanded quickly, and has no strong smell. It feels supportive yet soft, and I’ve been sleeping much better since I got it. Great value for the price!

Most comfortable bed I've ever slept in. I first gotten one for my daughter's bed and i liked, she's had it for 3 years now and actually loves her bed. Its soft and yet hard enough for support. The foam does not indent like the tempur pedic mattress I've used before. I love that it does not have any springs. I do not feel or hear when my partner gets up or rolls in their sleep. And the material is nice to keep him cool through the night. This is the 2nd NapQueen mattress I get and will forever stick with it.

I recently took a chance on an inexpensive mattress in a box, and I must admit, it has far exceeded my expectations. Coming in at a fraction of the cost compared to big-name brands, this mattress has proven to be a pleasant surprise in terms of comfort and value. Upon arrival, the mattress was tightly packed in a compact box, which made the delivery process straightforward and convenient. Unpacking it was a breeze—simply unroll and let it expand. Although the initial plastic packaging emitted a noticeable odor, commonly associated with new foam products, I was relieved to find that the smell dissipated completely within a day or two. In terms of comfort, this mattress hits the sweet spot for me. It offers just the right level of firmness, providing ample support for my back while still being comfortable enough to ensure a restful night's sleep. The memory foam contours to my body without sinking too much, which alleviates pressure points and promotes proper spinal alignment. Durability-wise, the mattress feels well-made for its price point. The materials used seem sturdy and resilient, and despite my initial concerns about longevity, it has held up admirably so far. The edges are reinforced adequately, which prevents sagging and ensures a consistent sleeping surface across the entire mattress. One of the most appealing aspects of this mattress is its affordability without compromising on quality. It delivers on its promise of comfort and support, making it a great option for budget-conscious shoppers like myself who are looking for a reliable sleeping solution without breaking the bank. Overall, I am genuinely impressed with this mattress in a box. It has proven to be a smart investment, providing me with comfortable nights of sleep without any major drawbacks. If you're in the market for an affordable mattress that offers good value for money and the right balance of firmness, I would highly recommend giving this one a try.

The media could not be loaded. The quality is great! I was weary when unboxing it, but give it the 24 hours it will fully inflate to size. It’s is worth the money. It is very quiet and very FIRM. We weren’t used to memory foam beds but after having a couple weeks now it’s lovely. For 2 people it’s easy to unbox and set up. It’s doable with 1 person but might be difficult. For a mattress it’s on the lighter side which is a plus for me to be able to access under the bed.

The Nap Queen mattress is an excellent price for the comfort and size of the mattress. I purchased for guest room along with assembly yourself box spring and was very surprised how comfortable it was and that no bars could be felt even with the 8-inch mattress. The mattress has a nice firmness, while remaining plus feeling that a back or side sleeper could enjoy. My parents were the first to sleep on it and it was not too hot to sleep on and said they would be getting one to replace the one in their camper trailer.

It’s an okay mattress, nothing to write home about. Needed a new mattress prime day deals mattress was only 100 bucks. Doesn’t inflate all the way, only inflated to 7 inches instead of the eight. Super soft and comfortable but since it didn’t inflate all the way I can feel my bed frame through it. I’m just gonna have to purchase a mattress topper for it. If I paid full price I’d probably be more pissed but since it was a $100 dollar mattress I didn’t have high expectations any way.

I’m using this mattress on an adjustable bed as a replacement for a hospital bed. It’s a little firmer than I expected, which took some getting used to, but overall it does the job. It adjusts smoothly with the bed frame and provides decent support. Not the plushest, but definitely practical and comfortable enough for daily use.
