Here are my first impressions of this mattress. First for the price, I don’t believe you can beat it the description and sales point seem to be accurate. I didn’t want to purchase a very expensive mattress because I plan on relocating in a few years so upon researching I landed on this solution. After receiving the product I opened the box and removed the mattress, I stood there staring at it, I just bought a 60X80 pancake. I used the enclosed knife to remove the plastic vacuum sealed bag, worked well. Within minutes the mattress expanded to 85% fullness than continued over a short period to 100%. There was a faint chemical like Odor but nothing alarming and has diminished after 24 hours. I have to report my first sleep was heaven, I fact my sleep was so deep my dreams were twenty years old (the memory foam). The mattress is semi firm and effective for side or back rest. I don’t consider this to be a mattress for sitting on however I hope it holds up well - only time will tell.Update June 21: I’m still satisfied with my purchase. The mattress provides me with a better sleep then the $900 one it replaced. I read a post reporting there was bug beds on the delivered mattress, I personally don’t believe they came from the factory or somehow got into the vacuum sealed bag. Bed bugs live on blood and prefer to attach themselves to mammals at rest. If you’re going to reuse an old box spring inspect it throughly top and bottom. Vacuum then bag it in a bug Proof zipped cover. Clean the walls and the floors as well. Wash all bedding and lastly don’t eat cheese and crackers in bed... Very nice mattress! Great value for the price. When we receive it, we were so surprised that the mattress expanded fully within 40 seconds. It’s medium firm and comfy. We’ve slept on it for a couple days and we really love the way it conforms to our body. All around this was a very good investment and I’m extremely happy with my purchase. Firm but gives. I'm fat and comfortable sleep has eluded me for couple years. I layed on my stomach, my side and got some great sleep! Had it for a week now and it's helped us so much. For the money? Win win win! The bed mattress is super comfortable and perfect level of support. not too soft and not too hard its just right. My husband and I both have back issues and it has helped us tremendously! I have not woke up with a backache since I bought it! This is the best mattress I have ever used，Great mattress at a great price. Would recommend to my friend and family! I was looking at many budget memory foam mattresses, and ended up buying a Zinus. That was 3 months ago, and I still have not received that one. I have asked for my money back, and am currently waiting patiently. In the meantime I purchased this Secretland. 5 days later, it arrived!It's only been one sleep so far, but I felt like I should write a review already. Obviously I'm not sure how the mattress will hold up over time, but it seems like a very well made mattress. I have heard of memory foam mattresses having a gassy smell, but mine at least had none at all. Didn't take long at all to expand either. Maybe we should have waited longer, but we slept on it about 7 hours after opening it, and seemed fine. The mattress was firmer than I was expecting which is a good thing. I'll say it again, the quality of the mattress is A+ Ordered the queen size 12" mattress, and I'm so glad I got it! My previous mattress was less than 5 years old, but hated it from day one. Finally, I was sleeping on the couch for the last few months, then decided to order this mattress. Heaven!!! I've had spine surgery and back pain for 12 years, and I can finally sleep for longer than an hour or so before waking up in pain. My hip doesn't go numb, my shoulder doesn't ache. Fast shipping, easy to manage (by my husband) box. Just emptied it into the frame, slit the plastic open with the provided tool, and the mattress expanded fully in a couple of minutes. I'm very sensitive to smells, but didn't encounter any, even though people told me to expect it for a little while. Totally happy with my purchase, will definitely buy another if needed, and highly recommend it. We love this mattress it's the best purchase we made. I have recommended it over and over to many friends and family members.For a mattress that is compressed and rolled up you wouldnt expect it to be so comfy but it really is! The quality and price of this mattress cant be beat, our daughter says she slept better than ever after getting it! So far so good. Set up was easy, shipment was great and product looks and feels exactly how it was described. Will give in update in 6 months but so far very comfy and great quality !!!!!
