I was very anxious/nervous to try this bed. I have never had a full memory foam mattress(bed in a box). We ordered King size, which we've never had before(best idea ever), as we always have littles sleeping with us. Assembly of the smart base was quite easy. The directions were straightforward. The opening of the mattress was a bit chaotic, but I think that also has to do with the size and me being tiny trying to do it alone. I did not notice a scent from the mattress, which they said may be a problem for people. Once opened, the matress fluffed up with no issues. It fits completely on the smart base. The smartbase gives about a foot high of storage space beneath it, my kids have been using it as their hideout/tunnel. We love the amount of space we have. The memory foam does cradle you quite nicely. I prefer a firmer bed and my husband prefers softer. This mattress is satisfactory for both of our needs. We haven't noticed the "cooling effect" as much. I do believe that is because our previous bed had a cooling layer, so this mattress it isn't as prominent. For the price and what you actually recieve, this is a great set. Which I do believe will hold up quite well. Excited to continue using this bed set.

Zinus Night Therapy Green Tea Zest 12" Memory Foam Mattress arrives in a large box ready to use. The box is a little awkward to handle without someone to help, but certainly not more than a regular mattress. The mattress is tightly rolled in a clear wrap, so be very careful when opening the box with scissors or a knife. Upon unwrapping, the mattress begins to expand pretty quickly. Within a few days, it is completely expanded (although I would follow the 72 hour rule before actually using). I did not have any real issues with odor, but we left in a well ventilated area until ready to use. My son loves his new mattress. We have all taken turns testing it out, and it is quite firm with just the right softness. We have already ordered another for another bed in our home. For the price and delivered to your door, this is a win-win!

It's in a guest bedroom so I don't sleep on it. just watch TV with the Grandbabies.

Excellent night's sleep and just the right amount of firmness for us.

It is very comfortable and good

Mattress did not inflate to full 12 inches

This bed mattress is very comfortable. We use it in our guest room and we get asked what kind of mattress they are sleeping on.

Only had it a few days and the memory foam layer is separating from the rest of the mattress not very happy

It's more firm than we expected for a memory foam mattress, but we're dealing with it and we're all waking up without pain so it works.

Zinus 12" memory foam mattress is very comfortable according to my oldest granddaughter who is in college.She said to give it a 10 out of 10.
