I ordered a full size bed. I like the bed is true to size. I waited the allotted time for the bed after being compressed to fully open and set up. That took around 48 hours for the bed to relax back to it’s position after being compressed in the box before I could fully use it. Though I have to say it looked like it came up immediately except for it’s corners. I also took it out of the box per instructions of the first 72 hours after receiving the mattress. I am still waiting for the corners to fully come up. I found the bed made well. I like that the edges are sewn well. I like the color of the bed. I found the cloth to be a medium grade that is on the top of the mattress. The euro top cushion on the top is nice. It gives me extra support and comfort for a good nights sleep. I found that the mattress is a little more on the firm side. This is the way I like my mattress, to soft gives me a back ache. I like that mattress gives my back the firmness it needs. My husband and I found that we did not sink in toward the middle as some beds do. I like it is silent, there is no creaking noise with it when I am moving around at night or the husband is moving. My sheets fit on the bed well. I like that the coils seems to be well made on the bed. I think that is a affordable bed. I found the mattress is not to light weight. I like it seems to be pretty durable. I am hoping for many years of use with this bed. I have enclosed pictures so you can make an informed decision based on your own personal needs. Yes, I would recommend this product. ... show more

    • Excellent quality
Style: 12 inch Size: Full
This 12" full size hybrid mattress is excellent quality, well made, and super comfortable. I needed a new mattress in our son's room since he destroyed his old one due to jumping on his bed, which caused the springs to poke through the mattress material (which made me mad, considering the mattress is only 4 years old). This mattress has blown my expectations away. It comes vacuum sealed and rolled up, allowing for easy moving and transport. Once we got it up to his bedroom, we were able to easily cut open the plastic with the included tool, AKA, letter open. To my surprise the bed sprung up fast and he was able to sleep on it the first night. He said it's comfortable, in the middle between soft and firm, but more on the firm side. ... show more

    • Good Value, Comfrotable
Style: 10 inch Size: Full
This is a real mattress that is surprisingly comfortable and very well priced. It's a hybrid with foam and springs which is my preference. It is medium firm and everyone who has slept on it finds it comfortable. A 10 inch full size seems small for two people or a big person, but as a spare bed for single guests, it works well. It would work for a child too. At this price point I don't know that it will last long nightly use by an adult but at this price, it is a very comfortable choice for occasional use. ... show more

    • Impressive
Style: 10 inch Size: Full
This is one of the best bed in a box mattresses I have purchased (out of a handful). Really can tell there are multiple layers with the top adding a nice thickness that a lot of these mattresses don’t typically have. My kids love this one in contrast to their previous bed in a box mattresses. Good quality and seems like it will last. ... show more

Great for my spare bedroom. This is a hybrid mattress. Roughly 10 inches. Not soft. Not extra firm. Kinda a medium feel to it.

    • Comfortable and well made
Style: 12 inch Size: Full
Arrived very well sealed and quickly. The mattress expanded to its intended size about 36 hours after removing it from the vacuum sealed package. It's for out guest room but I slept on it one night and it was very comfortable; firm without being hard. The only reason I removed a star is because the price is high. I'm pretty sure you can get the same one from a different seller for about $100 less. ... show more

This mattress easily inflated and did not take as long to reach full thickness. It is absolutely comfortable and gives a great support for my back. I highly recommend it.

    • Great mattress, perfect for spare bedroom
Style: 10 inch Size: Full
The Ruoysun Full Size Mattress has been an absolute dream for our spare bedroom! This 10-inch hybrid mattress, delivered conveniently in a box, has exceeded all expectations. The combination of gel memory foam and individually wrapped pocket springs provides a perfect medium-firm feel that's comfortable for all our guests. We particularly appreciate the excellent motion isolation, which means no one disturbs their partner during the night. The strong edge support is another fantastic feature, preventing any rolling off or sagging. Most importantly, everyone who has slept on it raves about the pressure relief and how well they slept. For the price, you simply can't beat the comfort and quality of the Ruoysun mattress. We highly recommend it! ... show more
