  • Great mattress!
Size: Queen Style: 14 Inch
Bought this because my 15 year old needed a new mattress with support. I am loving the hybrid mattresses. Took out of the box and as I removed plastic it popped up to rid full 14" almost immediately. No bad smells. It has some bounce to it but not much. It's firm but medium firm, it has some give to it. We have high bed frames also so some of the give on the sides that others have commented we like because it helps us get down off the mattress lol. I plan to purchase one for my bed soon as I beee a new mattress. I really suggest you buy this. Great price, fast delivery and can use right away. Great support but cozy too. ... show more

  • SIMARTH King Mattress 14 Inch: A Comfortable and Affordable Option
Size: King Style: 14 Inch
I recently purchased the SIMARTH King Mattress, and I'm quite pleased with it. For the price, it offers a comfortable sleeping experience. Pros: Comfortable: The 14-inch thickness provides adequate support and cushioning. Affordable: It's a budget-friendly option compared to more expensive mattresses. Unexpected bonus: I was pleasantly surprised to find that it has springs, which adds to the overall comfort. Cons: Not as luxurious as high-end options: While it's comfortable, it may not match the plushness of premium mattresses. Overall: If you're looking for a good quality mattress without breaking the bank, the SIMARTH King Mattress is a solid choice. It offers a comfortable sleep and is a great value for the price. ... show more

  • Total comfort and perfect support for a good rest
Size: Queen Style: 12 Inch
This 12-inch Queen hybrid mattress has been an excellent investment. The combination of memory foam with springs provides a firm but very comfortable support, ideal for sleeping well all night. It adapts to the body without sinking too much, relieves pressure points and helps keep the spine aligned. In addition, you don't feel the movement if the other person moves. It arrived well packed, it expanded quickly and without bad smells. Now we sleep much better! ... show more

  • Such a great product for the price
Size: Full Style: 12 Inch Medium Firm
First time trying a mattress in a box and I'm loving it! The only complaint I have was with shipping. They delivery driver (ups) dropped it next door. Ups shipping for me has always been awful. I just don't see how hard it is to read a number on a house. Can they just not comprehend it or something? I'm including the shipping details because luckily we have good neighbors and I walked over next door to bring it home and the box was absolutely destroyed and on one end there was almost a whole roll of packing tape keeping it shut. I picked up the box which was very heavy but not heavy enough for me to carry it home. Half way In between my home and the neighbors the box ripped making the mattress fall out and it started to roll. I managed to get it home and upstairs where I put it on the frame and opened it. When I unrolled it there must have been a hole somewhere because once un rolled it started hissing and expanding on its own. Then I cut the plastic off and let it expand on its own. Also a side note, the box was labeled with the sizes like twin, full, king, queen but it wasn't marked so I'd suggest measuring the box to make sure it's the right size you ordered. It says on the box to wait 72 hours before sleeping on it but honestly I couldn't help myself and I only waited about 10 and it didn't seem to affect it any. The bed its self is the perfect balance between soft and firm however the edges of the bed are extremely soft. For elderly people it might not be the best as they often have to sit on the edge of the bed and might slide off. This is such a great product and I am VERY happy with this purchase. I would definitely recommend ... show more

  • Great quality.
Size: Queen Style: 12 Inch
It arrived in a timely manner but was stained near the end of the bed . A very nice quality and super comfortable. Has perfect support and just the right size. Amazing product I just wasn’t happy about the large stain on the corner.
