5.0 out of 5 stars Five-star mattress that is worth every penny
By Vlad on July 20, 2019
This is my review for:
AmazonBasics Cooling Gel-Infused Memory Foam Mattress, 12-Inch, Queen
Unboxing:
I was super excited to receive the mattress, but when it showed up, I got a bit worried. It weighs about 75 lbs. and it looked like every single UPS person that handled it must have taken their frustration out on it. The box was beaten, torn, and filthy. I would not want to drag it inside on a nice carpet. I cut open the cardboard box outside on the porch so that the nasty cardboard wouldn't be inside. I was pleasantly surprised to find that the mattress inside was in perfect condition. The mattress itself is of course vacuum packed and then it had a generous wrapping of heavy duty stretch wrap on top of that. I carried the perfectly wrapped mattress inside.
Getting it ready to use:
I got it all unwrapped and laid it out flat and cut open the bag along all the edges. It started to puff up immediately. It was fun to watch it grow into a full-sized mattress in about 5 minutes. The instructions mention that it can take up to 72 hours to inflate, but in my experience, it took considerably less. I would say it was to 90pct of its height within an hour or two, and fully expanded within 24 hours. I would say it is quite conceivable that you could unpack it during the day and sleep on it that night. I was a bit concerned that the mattress, like any man-made foam product would have some smell but was I ever pleasantly surprised. Immediately after opening it there was little to near zero smell with my face literally buried in it. One of my nephews swore that it smelled faintly like chocolate but the rest of us could detect nothing.
Using it:
My sister-in-law who will be using it the most, since this is for the guest bedroom has only slept on it a few nights now, but she is completely in love with it.
Other Thoughts:
When looking at this mattress price versus performance to this point, this one is a bargain. I will come back and update the review if there are any problems in the near future, but as of right now this is a solid 5-star mattress for sure. It also supports local economy as it is an amazing product proudly made in the USA.

Update:
Over a year has passed and I am still very pleased with this mattress. This mattress is still amazing and the sample size is bigger now. My sister-in-law slept in it for a bit over a month, and my sister slept in it for about a week when she came over. Additionally, my wife and I slept in it for about a week, when my mom came over to visit. Those are a bunch of thumbs up, thus we definitely recommend it!
