    • Medium to Firm
Size: Full Style: 12 INCH
So far I’m really liking my new full size mattress. That being said. I searched for plush because I didn’t want to sleep on a firm hard mattress. It is NOT plush but is absolutely between medium to firm. I’m 52 5’5” and weigh 157 lbs. If you are taller and heavier I think the mattress would feel much softer. In the end I would buy it again. I do not wake up stiff or sore and am getting very restful sleep. I have also recommended it to a gal friend for her guest room and she ordered it as well. The value for the money is excellent. Quality thus far is excellent. Sleeping temperature is also very nice. Oh it also came expertly packaged and has fluffed up nicely. I have NO ridges or valleys. ... show more

After sleeping at my daughter’s house on her new Crystli mattress I ordered one for myself. I have now slept peacefully with no more morning back pain on my king 14 inch deep mattress for one week. I found the quality amazing and the price unbelievable compared to brick and mortar stores. I’m a huge believer in mattress in a box! ... show more

    • Great for the Price
Size: Queen Style: 10 Inch
***ATTENTION ALL WOMEN INTERESTED IN THIS MATTRESS*** U was nervous to buy a mattress online, but I don't regret it! I needed an affordable mattress for my new apartment, and this was in my budget. It arrived on time and the packaging was a very sturdy long box. I will say I moved this into my second-floor apartment by myself and it was HARD. The box was incredibly heavy, there were no holes in the box to make lifting easier, and I had to cut my own holes into it for purchase. I hurt myself moving this thing by myself, so please get help if you're able! I ended up doing it on my own, but I wouldn't do it again. The mattress is in an airtight seal. It's packaged tight inside the box, so you'll have to cut the box open or turn it upside down to get the mattress out, roll it out onto your bed frame or floor (I recommend the frame because it is HEAVY) and cut the seal. There was enough space in the seal that I didn't worry about cutting the mattress it is fairly easy to let out. It takes 2 full days to inflate but I waited 4 days just to be safe. It is a comfortable mattress, but it isn't like sleeping on feathers. It's a very firm mattress despite the pillow top but I don't feel like my back pain is miraculously better. I've slept on more comfortable mattresses, but for the price it's great and it's the best mattress I've found. I did not buy for a luxury; I genuinely just needed a bed. I've had it for 7 months and have rotated every 3 months since I got it and have had no problems. I'd 100% buy this again, just with some help! ... show more

    • Comfort Mattress
Size: Full Style: 10 INCH
Bought this mattress back in Oct 2023, when my dad had to come and stay because he was recovering from an emergency hospital stay… Lo and behold he loved the mattress and the bed frame (was bought separately here on Amazon) enjoyed the cooling double sided bamboo pillows also….Said that it’s the most comfortable nights sleeps he’s had in years… he especially enjoyed that the mattress height and frame height. He said he didn’t feel the need to try and turn every couple of hours to get comfortable because he was… He said it is amazing that this little purchase made such an amazing difference in his recovery… THANK YOU !!! Now everyone else who has stayed by my home has enjoyed this mattress and bed frame and the pillows (bamboo cooling pillows): well everyone that has been here have thoroughly enjoyed appreciated the comfort and style and tell me I should open a B & B and have asked for the links for these items… and I have gladly given it… Best purchases I ever made. Thanks to the company and Amazon… I may still open a B & B…😀😀😀 ... show more

    • World’s best mattress!!!
Size: Full Style: 10 INCH
This is the PERFECT mattress! It’s simply underrated!!! This is better than a $2,000 mattress! It took less than a minute to get into shape, it’s very lightweight, and it’s so comfortable! It’s been about two weeks since it’s arrived, and it still feels like it’s the first day! My whole family loves this mattress! There are no springs poking out of anywhere, and it’s very firm! The package was so small, I doubt a small TV could fit in it. But once the mattress was put into place, it instantly became huge! It’s like a big, comfortable, compact, marshmallow! This mattress can help you get more deep sleep! I love this mattress so, so, so, SO incredibly much! I absolutely recommend buying this! One of the best mattresses I have ever slept in and bought! It also stays cool all day and night long, whether or not there is a bed cover! 😊 ... show more

My son really enjoys the Full Mattress. It offers just the right amount of softness for comfort. The memory foam conforms to his body shape, offering support where needed while still feeling plush. The 10-inch thickness provides a good balance of comfort and support, making it suitable for various sleeping positions. Overall, it has been a great choice for his comfort and sleep quality. I would recommend this mattress to anyone looking for a comfortable and supportive option for a good night's sleep. ... show more

    • No side wall structure
Size: Queen Style: 14 INCH
We bought this mattress as a possible replacement for our current mattress. We didn’t really need a new one but decided, if we didn’t like it we could put it in our guest room. Well, it’s in our guest room. The mattress is comfortable enough to sleep on, but there is zero side wall structure so don’t plan on sitting or laying near the edge of the bed. You’ll probably slip off the side. If side wall structure isn’t important to you or you’re buying this for a child, it’s probably a worthwhile purchase, but it didn’t meet our needs. ... show more
