Nice bed!
I ordered a queen. Came in a box. Opened up and let it set up for 2 days. This bed is a little heavy. Need 2 people to pick it up. The memory foam top is soft but not too soft. Its about 4 inches thick.The coils underneath give it good support. I am a side sleeper. Overall its a decent bed!

PERFECT!
This mattress is awesome. After trying one out in the mattress store and not wanting to pay 1300.00, I found it here. Husband and I are very very picky and was skeptical about a hybrid after having a pillow top for 20 plus years. But we do not regret buying this at all. Itâs not super soft, but not too hard. We wake up with NO back or leg pain anymore.I would give 10 stars if I could.

Deep Relaxation In A Box
I was initially quite hesitant about selecting a gel memory foam mattress, especially since I’d never slept on one before and wasn’t aware there were different thickness options. However, when my Queen Size 14″ thick mattress arrived, I was immediately impressed by its color and texture. Despite concerns from some reviews about the expansion process, I found it remarkably comfortable even after just a short time, especially compared to the uncomfortable bed at my temporary rental and the damaged mattress it replaced. The first night on it, I just lay down without a box spring on the assembled bed frame, and my body was the most relaxed it had ever been, leading to a deeply restful and restorative sleep that left me feeling both physically and mentally refreshed.

I expected more from Sealy
This is our 4th memory foam mattress. Our first hybrid mattress. The edges are “horrible”. You sit down on this 14″ bed and it squishes to nothing! It was supposed to be SOFT it is not. If you roll over in your sleep and get too close to the edge of the bed. You may end up on the floor. Our other beds were NOT name brands. Shame on you Sealy.

I understand why it’s a frequently returned item.
I can see now why this item is frequently returned. When it arrived, the box was open on both ends, leaving the mattress completely exposed. This raised immediate concerns about the productâs condition. As for the mattress itself, it’s extremely firm, almost rock-solid, definitely not the plush feel that was advertised. I was expecting much more comfort. In hindsight, I should have gone with my second choice, the DreamCloud mattress, which I believe would have been a better investment. I also hope this honest review isnât being removed by the seller, whom I contacted on Amazon about.

Disappointed
Unimpressed. Ive been mattress shopping really like the sealy I’d seen in store but needed a king so I ordered this model. It has not inflated to full size, the top part of mattress is hanging off if bed to one side and won’t get even. There is also no support around the coils of the bed on the outside so you can feel them through the mattress cover which is even worse since the mattress top is off center. Extremely disappointed in the purchase

Too soft:
This mattress is nice and comfy but does the support needed for to sleep on it!
