I can’t believe how comfortable this mattress is at such a great price! I’ve slept better in one month than I did all year on a different, higher end mattress and have been pleasantly surprised with its’ firmness, value and how well it inflated after arriving. By far the best purchase for the price! Love my new bed, you won’t regret yours!

What a great price! I wasn’t sure what we would get; I have always bought a mattress at a store before. Three weeks in I’m very pleased. True to their word it is extra firm. The hybrid combination of springs and foam isolate one person’s movements from the other well. Mattress cover material is of high quality: sturdy and soft . We got a king so unpacking it was a two person job. It didn’t take long; it was just cumbersome to maneuver. If you are a person who likes to sleep ON a mattress not sunk IN it, I recommend this one.

I recently bought a 12-inch King Cocoon extra-firm mattress for $320, including tax. Let me break down my experience in more detail to provide you with a comprehensive list of pros and cons. • It was delivered in a plain cardboard box. Normally, brand-name manufacturers have their brand printed on the box, along with all the necessary information. The box only contained a USPS label, weight, size, and instructions on how to open it. No additional information was provided. • Firmness (Firm, not Extra Firm): The comfort level is good and provides support, but it is not extra firm as stated in the description. There was no mention of firmness on the box or in the manual. • Price/Quality: In terms of value, I believe the cost is reasonable for what you get. I see the price of this brand fluctuates. NO idea why • Cooling: Is missing • Weight (approx. 120 lbs.): It is heavy, maybe because of durability and the use of higher-density material or more support coils. I suggest two people to unroll it. • Inflation (12 inches): It reached its advertised height, indicating that all layers fully expanded as intended and there was no permanent compression set. • No Smell: The lack of off-gassing (the chemical smell that sometimes comes with new foam products) is a major positive; the materials are likely CertiPUR-US certified or made with low-VOC (volatile organic compound) processes. • Motion Isolation & Edge Support: Yes • Overall: Fast delivery rounds out the positive experience with the mattress so far. Time will indeed be the ultimate test of its durability.

Very good!!! Buy it without fear. I was very scared at first. I had recently been diagnosed with a back problem. I researched a lot and finally found this mattress which, besides being affordable, is extremely good for the back, and I highly recommend it. I’m very satisfied with my purchase and I want to recommend it because I also searched a lot before buying. I looked for reviews, and I hope this review helps you too.

I got it a week ago. Too early to say but I like it so far. Came in small box which inflated quickly to a king size. (Always a fun to watch it swell) I ordered 12in extra firm. And it is good firmness. I was tired of those “firm” mattresses which by no means were firm. So this “extra” firm mattress is what a good firmness should be. I hope it just stays like that. Which I will come to know in few months.

I was skeptical to purchase an “extra firm” bed for a fraction of the price that big box stores usually charge, but I am pleasantly surprised! This bed is the perfect amount of firmness. I wanted a super hard mattress and this bed delivered! It provides support to me as both a back and side sleeper, too. I would recommend this mattress to anyone who wants a true extra firm bed.
