    • Very firm!
Size: Full Style: 8 Inch
Firstly, I have never purchased a foam mattress before so I cannot compare this mattress to others in its category but I will give my honest opinion here. I purchased this mattress for my one year old. Positives: This mattress had zero smells when it opened. I opened it midday and it was completely done inflating by bedtime and I felt comfortable putting it in my child's room by night time. The quality was wonderful and it is very light. The cover was a soft material and it had great quality foam with all the proper certifications. I was pretty happy with it upon opening. Subjective: This mattress is very firm. It does not have the support of a firm spring mattress since there are no springs. It would be like putting a memory foam topper on the floor - you have that small amount of give and it is very firm below that. The top two inches are that type of memory foam that sinks as a warms up so when you roll over at night you aren't immediately comfortable and if you have any back or hip pain and need a firm mattress, I would recommend looking for something with springs - hybrid mattresses are my favorite. The 8 inch may also be just too thin. My understanding is that the thicker mattresses have a thicker layer of the memory foam. I personally didn't mind the firmness so much, although, I didn't really love the feeling of shifting in the night and this is not something that would have worked for me in pregnancy as my hips got pretty sore from laying on my side all the time on a latex mattress - this would have been much harder on me. Regardless, I purchased this for my one year old but, unfortunately, he flipped and flopped and woke up frequently for a week before I traded this mattress for the one in the guest room (a hybrid mattress), which he slept completely soundly on. I decided to return this mattress and search for a hybrid, which will hopefully serve us better. This company did try to give me a 50% return because they could not take the full sized mattress back but I told them, within the 30 day return window, that was not acceptable. They gave me my money back but left the mattress for me to keep or donate, which was very nice of them. Four stars for quality and customer service but this mattress was unfortunately not for us! ... show more

    • TOO GREAT!!
Size: Twin Style: 8 Inch
These mattresses are so great that my twin grandsons don't want to get up in the morning!!! They just transitioned from youth beds to bunkbeds so I ordered these for them. The go to sleep quickly and sleep late in the morning! I love hearing them tell me how much they love their new beds!!

    • 12” is firm!
Size: King Style: 12 Inch
I received the mattress on 8/11, which was the day I was moving so in that process I wasn’t able to actually unfurl it till the end of the day. However, it puffed up almost immediately. There were no sagging corners, the bed was very clean, and it was perfectly sized to a US King. After sleeping on it I’d say there’s only really some give at your pressure points, everything else is firm and springs right back when you move. I love this mattress so far. I spent months looking for one most suitable, especially because my boyfriend really wanted a firm mattress for his back and he loves this thing. Plus 12” King has really helped us get more room for our dogs to lay down without crowding us. If you want a firm large mattress, this is an absolute steal so far. I’ll try and update down the road since those are the kind of reviews that helped me during my long mattress search! (Huge bonus: I didn’t wake up with sciatic pain for the first time in months) ... show more

    • Comfy bed!
Size: Twin Style: 8 Inch
This bed is so soft and comfortable. It was easy to remove from the box and easy to set up. Was delivered to our door so it didn't require a large vehicle to transport.

    • Cannot believe how happy I am with this bed
Size: Queen Style: 10 Inch
I purchased the Dyonery Queen green tea infused mattress and can't believe how comfortable it is. It's the perfect balance of body contouring softness on the top later with perfect firmness below. I haven't slept this good in years! This is one of the lowest cost mattresses I found on Amazon but don't let that stop you from buying it, this mattress is incredibly comfortable. ... show more
