This bed is thick and just the perfect support, so soft and yet not overly soft as it cushions firmly enough to let you get a really great nights sleep. I LOVE IT! It did Not smell weird as some springless mattresses have in my past when ordering other kinds. 💖 This is the best mattress for a very affordable price. I will be ordering another one for my family asap. Forgive that the photo is not of entire bed as just moved into apartment and just took photo enough to see that its not some thin pad as some reviews may imply. It quickly puffs out after unboxing and its so comfortable and quality natural bed. HEALTHY PERFECT BED YES :)

I bought this mattress a few years ago. I'm HAPPY I took the chance on this one. And now that I've been on the hunt again for an affordable mattress, I decided to review it because we are buying it again, this time for my daughter's apartment at college. All I can say is, wow! It has completely blown away my expectations. I had previously bought the twin size for another room, and it was a huge hit, with guests consistently complimenting its comfort. This mattress proves you don't have to break the bank for a great night's sleep. The unboxing experience was incredibly straightforward. It arrived in a surprisingly compact box, which made getting it into the room effortless. Unpacking was a cinch, just a few snips, and it quickly began to inflate. While there was a slight, new-foam smell right after unrolling, it vanished completely within a day, which was a huge relief. What truly impresses me is the perfect balance of comfort and support. The memory foam cradles my body without that "stuck" feeling, providing excellent pressure relief. It's firm enough to support my back and maintain proper spinal alignment, yet soft enough to feel cozy and inviting. It's the kind of mattress that you sink into just enough to feel relief, not a black hole. For the price, the build quality is outstanding. The materials feel durable and well-constructed, and after several weeks of use, it doesn't show any signs of sagging or wear. The reinforced edges are a nice touch, giving the mattress a solid, substantial feel. This mattress is a prime example of exceptional value. It delivers on every promise, comfort, support, and durability, without the hefty price tag. It's the kind of purchase that makes you feel smart and savvy. If you're looking for a reliable, comfortable, and seriously affordable mattress for yourself or for guests, I can't recommend this one enough. It's easily one of the best purchases I've made this year.

A decent mattress for the price. Moderately firm without feeling like I'm laying on a brick while not sinking in either. Edges will collapse if you sit on them, but that's to be expected from an 8" mattress. Overall, it serves its purpose and is comfortable.

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!

The media could not be loaded. Fiberglass!!! I purchased this mattress in March 2023. On November 2, 2025, I decided to remove the zippered cover and wash it. The manufacturer stated that the mattress cover is removable and washable. However, Nap Queen failed to disclose that the mattress contains fiberglass. After washing, I put the cover back on the mattress. Subsequently, I washed my family’s clothes in the same washing machine: underwear, sweatshirts, long-sleeves, pajamas, etc. We made the bed, and my son put on pajamas that had been washed and dried in the dryer after washing the mattress cover. He started scratching himself, but we didn’t immediately realize the cause. The next morning, he complained that it felt like he was being pricked with needles! We inspected his pajamas and found them covered in shiny fiberglass fibers. It was horrifying! Then I realized the problem was the mattress. Upon inspecting the mattress, it was full of fiberglass! The fibers are visible only in the dark with a flashlight — everything sparkles! My child was breathing in these fibers, sleeping all night in those pajamas. We inspected all the clothing washed after the mattress cover, and everything is contaminated with fiberglass. This is a complete nightmare! During the process of removing the cover, loading the washing machine, and putting it back on the mattress, we were exposed to these fiberglass particles. This is an outrageous situation! I have filed complaints with Nap Queen and Amazon and am awaiting their response. I do not know how many more fiberglass microfibers have spread throughout the house! It is clearly visible that the entire mattress sparkles on the underside. I am not touching the mattress topper yet, as I am waiting for a sealed bag for the mattress. Unfortunately, I can attach only one video. It is very difficult to capture the fiberglass on photos, as it is clearly visible only on video when illuminated with a flashlight in the dark. I have lots of videos showing the contaminated clothing, as well as the contents of the dryer filter, which contains thousands of tiny fiberglass fibers. Additionally: I used to praise this mattress and recommend it to everyone — I truly thought it was the best. That was until I washed the removable cover (which the manufacturer clearly describes as “removable and washable” without a single word about fiberglass). Now my new friends are fiberglass particles. I’ve been fighting this for a week already and had to say goodbye to many of my belongings.
