SimmonsGel Memory Foam Mattress - 12 Inch, King Size, Plush Feel, Motion Isolating, Moisture Wicking Cover, CertiPur-US Certified, 100-Night Trial

I had a tween size for a while and often I was moving from my king bed to the twin because I was able to sleep better. Lastly, I decided to replace my 1 year old king size mattress with a Simmons one and I am thrilled for the decision I made. I just love it. It's soft and molds on my problematic back like a glove.

For me, this mattress is just right. It has just the right amount of memory foam feel but I don't sink in too much. After a few days of adjusting to the feel, I found myself sleeping through the night much longer without waking up. The comfort vs. value is very good. There are probably better mattresses that offer better coolness, etc. But I wasn't looking to get everything all in one. It's easy these days to add a cooling cover. What's important is to get the firmness / plushness just right. For that, I give it 5 stars.

It was great for a while, then it started getting low spots on the left edge. Now 1/3 of the mattress is lower than the rest when I lay on it. I have a full size bed and I sleep in the middle of my bed. So I feel like I’m falling off the edge most of the time. It wasn’t a very expensive mattress but I expected it to last for a long time. Sleep quality is terrible, and now I’m waking up 4-5 times during the night trying to get comfortable and when I’m sleeping on the ridge of the lower area my back hurts. Probably won’t keep it much longer but I can’t afford to buy another one right now.

We like the mattress, but it is an ordeal. To make it simpler for the next buyer, here’s what I would suggest. Have some sort of platform frame ready in advance. The metal frames are fine, but need a platform base, due to their slats being too far apart. Buy plywood. Have it divided in half for a large bed. Lumber stores will cut it for you. Beware of plywood that has odors. Paint will help.Now for the mattress. Ours came with no instructions on which side was the top, width, etc. We figured out that the side with zippers exposed near the edges was the bottom. Our mattress was king size and very heavy. Two of managed to move it, but a couple more people would have been helpful at the beginning. After careful removal of the plastic wrapper, the mattress did magically expand. I’m sure you could sleep on it after a few hours, BUT the foam does have a strong enough odor that it’s best to open the windows and let it air out for a week or so.Finally, we are enjoying the mattress. We find it comfortable without too much firmness or softness.

I've been thinking about purchasing a bed like this for awhile and the reviews were all over the place on this type of matress. I finally bit the bullet and purchased this matress almost 2 months ago and my sleep quality and bad back have been thanking me ever since. I put this bed up in the morning and yes there was a smell to it. That smell on mine was gone by the time I went to bed that night. I didn't measure the height of the bed but did notice the cover was tight so I'm assuming that it raised to the manufacturer height and would recommend it to others. My only concern is the sides of the bed not feeling ridged enough when you are sitting on it putting on socks or something to that nature.

This is probably the best mattress I've bought and at more than half the cost of an industry-leading brand. It's perfectly plush - not too soft and not too firm. I can't feel my partner tossing and turning on the other side of the bed at all during the night. The smell was pretty bad for the first couple days after unwrapping, but it completely dissipates within two weeks. Keeping my bedroom window slightly cracked during the day helped tremendously. This is a great memory foam mattress without having to pay for the swanky marketing like other popular online brands. Probably the first night of quality sleep I've had in my own bed for 5 years!

It is hard to describe the firmness level of a bed but I would put this in the medium area. You slightly sink into the mattress. Everything seems to be as advertised. There is a smell from the mattress for about 7-14 days but it disappears after that. I've only had it for 4 or 6 months at this point but so far I would buy it again

I love this mattress it is comfy and economical. I got it for my Murphy bed and it is very comfortable and we slept well on it.
