The bed is very comfortable. The firmness is perfect for me. And it expanded just right. It was delivered in a timely manner. Overall is definitely good quality for the money we spent on it. It has helped me with my back pain issues for sure.

I got the 14 inch mattress, queen. All of these reviews say it you can feel the medal in it or whatever no that is not it. It’s thick it’s comfortable. I gave it over a day to set up because I know that’s important. Other than that. It was great. I let it lay flat on my floor, so that way it wouldn’t mess up the sides when it was decompressing

I cannot believe what a bargain this mattress is. I went to mattress stores and laid on mattresses that were $2000 and didn’t feel as nice as this one. This one is the perfect amount of firmness, yet comfort all rolled into one. I cannot recommend this mattress highly enough. If you’re looking for a firm mattress, that is not uncomfortable, look no further. This is your mattress. If I need another mattress, this will be the one I buy.

The sides are a bit soft when sitting but overall the quality for the pice is spot on! Very comfortable and would buy again!

This was a Great choice. Its firm, but soft. It took 1 day for it to fully expand. well worth the money.

Heavier set guests can feel the springs on these guest bed mattresses. But they're plenty soft & comfortable for short term. Our 8 year old LOVES his. For kids/lighter folx - I think this is a good value. Not for plus sized or long term use.

This mattress is exactly what I was looking for!!! OK, so admittedly I wasn't prepared for how quickly it sprang out of the box and started" growing - I live in a small condo with a wall of windows, and these mattresses remind me of a certain brand of biscuits that come in a can: once you open them, they expand like crazy! I managed to corral it onto my adjustable base, on which it works perfectly! It is a tad squeaky; I believe having a headboard to help keep it in place will alleviate that. I cannot believe how comfortable such an inexpensive mattress is!! I had a (name brand) that was too stiff to work well with adjustable base; my neighbor gave me a (name brand) to try, but it was far too soft. This EEN mattress wins the Goldilocks award: it is "just right"!! The fact that the price is just right is a huge bonus! I know it is daunting to purchase a mattress online, but for what it's worth, I suffer from severe chronic pain in my cervical swing, lumbar spine, and SI joints - what a JOY it is to wake up pain-free!!! I find it works best if I elevate the head of the bed ever-so-slightly, but that's a matter of personal preference. If you don't have an adjustable base, I'm sure you will still love this mattress! I am moving things out of my bedroom in my cracker box condo in the sky so I can upgrade to a king ASAP: I like to sleep diagonally. I don't think you'll be disappointed with this one...I'm thrilled with it!

It claims firm, but it is actually soft. The Memory foam layer is very thin, and makes weird wavy wrinkles. These wrinkles are visible even with a fitted sheet on. Very disappointed. I wish I never opened the box, but at this moment, it is too late to send it back. The edge is not firm at all. When I sit by the edge, it sinks badly. Now, I am stuck with this bulky garbage.
