Features
- Smarts Coil Individually Wrapped Pocket Springs: The Avenco hybrid king mattress features hundreds of individually wrapped pocket springs that effectively minimize motion transfer. This is particularly advantageous for couples, as it helps prevent one partner's movements from disturbing the other, creating a serene sleep environment where everyone can enjoy a restful and undisturbed night.
- Pressure-Relieving Comfort: This 12 inch king mattress is designed with individually wrapped pocket springs that reduce the risk of sagging while offering optimal support, helping to maintain the natural curvature of your spine. The coil system enhances air circulation, preventing heat buildup and ensuring a cooler, drier sleep surface for a more comfortable experience.
- Environmentally Friendly Comfort Foam: Crafted with CertiPUR-US certified foam, this hybrid mattress effectively eliminates unwanted odors and regulates temperature, ensuring a clean and dry sleeping environment. Additionally, its hybrid design offers edge support on both sides to prevent sliding when sitting on the bed's edge.
- Certified Safe Quality: All Avenco king mattresses come with CertiPUR-US certified foam and OEKO-TEX certified covers, ensuring that the materials meet rigorous health and environmental standards, providing consumers with a safe and comfortable sleeping experience.
- 100 Nights Trial & Warranty Service:This 12 inch king mattress includes a 100-night risk-free trial and a 10-year limited warranty, giving you peace of mind with your purchase.

The media could not be loaded. I have always chosen memory foam mattresses before. This time watching this for a long time, I chose this medium-firm spring mattress. The number of spring coils is sufficient and it has good support. What I like most is that it is not soft and the mattress is very breathable and comfortable. The spring mattress is just right and will not affect the people next to you when you turn over. It is really suitable for a friend who often suffers from low back pain. Of course, his low back pain has been relieved. He enjoys this spring mattress very much. The elasticity is really good ,(Not soft, not dented )My boyfriend likes it very much and it is worth recommending.

I purchased this mattress to go on a day bed and my son says that it's the best mattress he has ever slept on! so if you're looking for an inexpensive but high quality mattress I highly recommend this one!

Im not so sure about this mattress. On one hand it's soft yet firm and supportive. However, on the other hand it's created differently. There are wires that run back and forth through it which I'm guessing prives the fir support. You can't feel them when you're laying there but they do stick out of the sides and you can feel them there. I also find the edge of the mattress to be extra squishy. You kind of just roll out of bed in the morning. I bought it for my 4 year old who just outgrew his toddler bed. He seems to love it so im not planning to send it back but I'm not sure if I'd buy it again.

Not very comfortable after a while had it less then 4 months and already need to buy a new one.. that's a extra hundred dollars I don't have.. at first it was great but then you feel the springs so if you enjoy buying a new mattress every 4-6 months this is the mattress for you

We purchased this mattress for our ambulance company. It is currently in our crew quarters. Our crew fight to get this mattress. They say it’s the most comfortable mattress that we have ever had. The mattress came quickly and was easy to set up. Overall, it’s a great value for the quality that it is. As for the thickness, it’s absolutely perfect.
