The Avenco Medium Hybrid Mattress—offering you luxurious comfort at a more-than-reasonable price.This next-level hybrid design features cooling gel memory foam to keep you cool as you sleep, while its cool-to-touch top fabric offers a refreshing surface to rest on. Its durable springs bring a winning combination of medium-firm support and soft, sink-in comfort to provide a premium sleep experience. Expertly designed, this adult mattress features edge support for a sturdy mattress surface and added support (with no box spring needed). Individually wrapped coils to minimize motion transfer to help you stay soundly asleep throughout the night.

I purchased this mattress for a teen bedroom, and overall it has been a solid choice. It arrived compressed, expanded well after opening, and was ready to use fairly quickly, which made setup easy. The medium feel is a nice balance between comfort and support. It has enough softness on top to feel comfortable, while still being supportive enough for everyday sleep. The hybrid construction also gives it a more substantial feel than I expected for the price. I also like that it sleeps fairly temperature-neutral. The cooling gel layer seems to help, especially compared to traditional memory foam mattresses that can trap heat. The reason I gave it 4 stars is that it was a little firmer than I initially expected, so it may take some time to break in depending on your preference. It’s still comfortable, just not as plush as some buyers might assume. Overall, I think this is a great value if you’re looking for an affordable, supportive mattress that is easy to set up and works well for a guest room, teen room, or everyday use.. Jas H.

I have a unique setup where I have 2 queen beds together because I sleep with my 2 great danes and 1 great pyrenees. I needed to be sure this bed was supportive, with some bounce , because straight memory foam doens't hold up to the amount of weight that could be on the bed. THIS IS AMAZING. First the coils are stiff with tons of support. Exactly what I need! It's an honest 12" high which is important since I have a 12" mattress next to it and it was off in measurements, it would be uncomfortable. But most importantly its extremely comfortable. It is a medium to medium firm type feel and it's perfect. I will be getting a second one for the other side of my double-queen bed! All paws approve, too!. Megan. Eagle Lake, FL. Mon May 18 2026
