I recently purchased the Avenco King Mattress, and I am extremely satisfied with my choice. This 12-inch hybrid king-size mattress offers a perfect balance of support, pressure relief, and comfort. Allow me to share my experience and highlight its outstanding features.
Pros:
Support & Pressure Relief: The combination of memory foam and individual pocket coils in the Avenco King Mattress provides exceptional support while relieving pressure points. It maintains the perfect balance between firmness and softness, ensuring a comfortable sleep without morning soreness.
Cooling & Comfy Sleep: The mattress features gel-infused memory foam, which effectively dissipates body heat and prevents overheating during sleep. Additionally, the independent pocketed spring system enhances air circulation, keeping you cool and comfortable throughout the night.
Less Disturbed Sleep: The individually wrapped coils in this king hybrid mattress react independently to movement, minimizing motion transfer. This means you won’t be disturbed by your partner’s movements during the night. The non-woven fabric pockets also eliminate coil-to-coil friction, ensuring a quiet sleep free from unwanted squeaks or noises.
Buy with Confidence: Avenco provides a breathable knitted cover and high-quality foams that are CertiPUR-US certified. The cover feels soft to the touch, and the foams are durable, ensuring long-term use without any concerns of collapsing. Furthermore, Avenco offers a 100-night trial and a 10-year warranty, providing peace of mind and excellent customer support.
Easy Home Entry: The Avenco King Mattress measures 80″ L x 76″ W x 12″ H and can support a maximum weight of 700 lbs. It is compatible with most bed frames, including box springs, flat platforms, slatted bases, and even floors. Additionally, the mattress arrives conveniently in a box and expands fully within 48-72 hours, accompanied by only a slight new mattress odor.
Cons:
Limited Firmness Options: While the medium firmness level of the Avenco King Mattress suits most sleepers, it may not be ideal for those who prefer an extra firm or plush mattress. However, the balance it offers is suitable for a wide range of individuals.
Slight New Mattress Odor: As with many new mattresses, there may be a slight odor upon initial unboxing. However, this dissipates within a short time, and the mattress is odor-free afterward.
In conclusion, the Avenco King Mattress has exceeded my expectations in terms of support, comfort, and overall quality. Its combination of memory foam and individual pocket coils ensures a restful sleep, while the cooling properties and motion isolation contribute to an undisturbed night’s rest. With the added confidence of a 100-night trial and 10-year warranty, Avenco delivers both reliability and customer satisfaction. I highly recommend the Avenco King Mattress to anyone seeking a medium-firm hybrid mattress that offers excellent sleep quality.

The reason why I’m not completely satisfied with this mattress is because I like to sit up in bed and work on my laptop or you know use my phone and if you do that over period of time, maybe a few months the part of the mattress where you sit down is gonna have like a divot and it’s gonna be kind of like it’s gonna wear away and have like a little bit of a dip in the mattress, but if that’s not something that bothers you or if you don’t really sit up in bed, you just lay down that’s totally fine. I think you’ll have a great experience with this.

This is the most comfortable bed I have slept in, in a long while. I bought it for my sister and a few days after it arrived we tried it out and it was amazing. I went on to get abed down the road from a mattress store and paid $1000 for it and it didn’t even sleep like this bed! I’m writing this review 2 years later because I accidentally fell asleep while laying in this bed! I don’t really know what to think of a bed in a box when I ordered this for her because my sister is on the heavier side and I wanted to get a sturdy bed for her. This bed is legit, the sides do not sink and there is not dips in bumps in the bed after 2 years of constant use. I really was compelled to write this review because just a few minutes ago I was having some of the best sleep I’ve had in a long time. I would give this bed a 10/10. Also I did try and get another brand bed in a box bed and it was a disaster. The bed was way too soft and I couldn’t use it at all. I’m only recommending this brand and this size.

I’ve been sleeping on the Avenco California King Mattress for four months now, and I can confidently say it’s been a game-changer for my back problems. At 60-something, I’ve tested my share of mattresses, and this one checks all the boxes for comfort, support, and quality.
Firmness: It’s on the firmer side, which I prefer, especially with my back issues. The combination of pocket springs and memory foam provides great support without feeling like you’re sleeping on a board. It cradles my body just enough to relieve pressure points while keeping my spine aligned—something my chiropractor would definitely approve of.
Comfort: The hybrid design really stands out. The memory foam layer adds a touch of softness without sacrificing support, and the individual pocket springs prevent motion transfer. My partner and I can toss and turn without disturbing each other, which is a win for both of us.
Durability: After four months, there’s no sagging or unevenness. It feels just as supportive as the day I unpacked it. Plus, it’s CertiPUR-US certified, so I feel good knowing it’s made with safe materials.
Setup: Unboxing and setting it up was easy, although you’ll definitely need two people to handle a California King. It expanded to its full size within a few hours, and there was minimal off-gassing compared to other mattresses I’ve tried.
Overall: If you’re in your sixties (or any age!) and need a mattress that supports your back while still being comfortable, this is a fantastic choice. It’s firm, but not too firm, and the quality is impressive for the price. I wake up feeling refreshed, which, at my age, feels like a small miracle. Highly recommend!

I sleep on this mattress at an Airbnb. It was one of the best night sleep I had in along time, so I asked the owner of the Airbnb what type of mattress it was. And when I returned home I purchased it. Nice and soft
