    • I have had this mattress for 8 years
Size: King Style: 12" Pattern Name: Original Box
Review Image by Orbenth Orbenth
I purchased this mattress when I purchased my house 8 years ago. I had been sleeping on a 20 year old spring king size mattress. I have the 12” Green Tea version. King. I am a 36 year old side sleeper who weighs 140 lbs. My wife is a 27 year old side and back sleeper who weighs around 250 lbs. I have the pleasure of being able to tell you how this mattress compares with a Zinus 8” cooling gel mattress and a 10” Green Tea mattress. In the 8 years I have owned this 12” mattress not a lot has changed. It has broken in but not down. It is noticeably less firm than the other mattresses without being considered not firm. There are no lumps, dips, divets or sunken in spots. I would buy it again in a heartbeat. In fact I know 6 other people who have purchased this mattress solely because they house sat my dogs for me while on vacation and slept in my bed. So let’s break it down: I purchased the mattress and it came tightly rolled and compressed in a bag that was in a box. I dragged the box to my spare bedroom and dumped it out. I rolled the plastic with the bed in it out and carefully pulled the plastic away from the mattress before carefully cutting along the seam in a quick motion with a box cutter. It immediately began to inflate. I pulled the plastic complete off and left it on the guest room floor. At the time I had just purchased the house. The carpet was clean and the only other item in the room were 3 moving boxes. I opened the 2 windows in the room. It was spring in SC so about 80 degrees. I left the room and continued to clean and unpack. I checked on the mattress about 6 hours later and it looked fully inflated. The room had a smell. It was very light and smelled like new foam as to be expected. I went along and plucked at the corners which were all still not fully up. Left the room and cleaned. I checked in it again before going to bed that night. The bed looked fully inflated, including the corners. I did not touch it. I went to bed and left it alone until that next night giving it almost a full 48 hours. I dragged my old mattress out of my room that night and leaned it against a wall in the spare room and then with the help of my then girlfriend, took the new mattress and placed it on my bed frame. (Which is an adjustable bed frame. More on that later.) there was no longer a smell. I grabbed my old sheets which fit on it perfectly even though this mattress is 12” and my old one was 6”. Grabbed my comforter and pillows and me, my girlfriend and 35 lb Australian cattle dog Beaux and 6 lb chihuahua Wiggles lay down. Heaven. I was 28 and weighed 115 lbs at that time. I had hurt my back at work tripping over a cord while carrying a heavy load when I was 23. My back had never been the same. For the first time in 5 years I lay on that mattress and no longer felt the pressure in my back. Or the constant searing pain. I do not sink into it. It’s by no means cloud like or marshmallow plush. On a scale of 1-10 with 1 being most firm and wooden plank like and 10 being marshmallow soft where you sink and get trapped this is a 3-4. It relieves pressure points but isn’t hard. I don’t bend when I lay on it but can feel my hip and shoulder go in. I don’t get very hot on it and I’m a very hot, very light restless sleeper. Any movement, light, sound, breathing will wake me up. Basically I’m just really bad at sleeping. It’s very good at not transferring movement so my girlfriend could roll or move and I wouldn’t wake up. When I bought the mattress I also got a waterproof cover because Wiggles was 14 and had seizures. Sometimes he would wet himself during the seizures so the protector could protect the mattress. It doesn’t crinkle and you can’t feel it, but even 8 years later the mattress looks like the day I drug it onto the bed. It bends on an adjustable base but is thick enough that it doesn’t bend all the way. The base also vibrates to massage your back. I can feel it through the mattress as well though it is very dampened. Sexy time is no different on this than with a spring mattress. You don’t sink in, there is less bounce and no squeaky springs. Fast forward to 2020. The pandemic. I am now 34 and weigh 155 lbs. mattress still feels and looks the same even with weight gain. No bumps or lumps and not hot, unless it’s summer but no matter what mattress you have you’re gonna be hot when it’s 106 degrees outside and the ac on your 102 barely insulated house is struggling. My spare room is no longer empty with just 3 boxes. It’s now a whole guest room. And it also has a Zinus bed frame and 10” green tea mattress. 10” compared to 12” is a little bit on the firmer side. Now a 2-3 on that scale from earlier. Still pressure relieving but motion transfers a little more. Beaux was testing it out with me and rolled and I could feel the bed jump. Guests still absolutely love it and talk about buying one. I always take them to my room so they can lay on mine and tell me if they feel a difference. They always end up choosing the 12” and buy it for their home. I have slept on the cooling foam Zinus mattress at 8” at my mother in laws house. It is not noticeably cooler but IS noticeably firmer. A 1.5 on that scale from earlier. Just shy of being a wooden plank. I was stiff the next day and my shoulders and torn back muscle aches. My advice is to go thicker on the mattress no matter your weight. Gives more pressure relief without giving you the sink. My mattress at 12” is by no means not firm but it’s also pressure relieving and not rock like. It’s now October 29th 2022. I’m 36 and weigh 140. Wiggles is no longer with us but the mattress cover and Beaux remain. Stryker the 50 lb Australian cattle dog has joined us. I write this review at 8:09 am, laying on the mattress. I slept for 7.5 hours and have no pains, stiffness or aches. I feel well rested. My wife is slightly snoring and just rolled a little and I barely felt it and only because I was awake to notice. I highly recommend this mattress and will replace it with another one exactly like it at the 10 year mark if it feels like it needs to be replaced. It doesn’t feel any different than the day I bought it now though. Maybe the 12-15 year mark if that’s the case. Sweet dreams and have a good night, y’all. ... show more

    • Great mattress. Comfortable for 2 fat people and 3 dogs.
Size: King Style: 12" Pattern Name: Original Box
EDIT: 3 month update.....I'm still leaving it at 5 stars. We have now had this mattress for just over 3 months and still love it. I am falling asleep faster, staying asleep and waking up feeling more rested. I have slept on both sides and even in the middle of the mattress and have equal comfort anywhere. I normally have 3 dogs hogging the bed and what's really nice is I barely notice if they get up and move to a new spot, even if it's right next to me. I no longer feel like my husband is doing backflips if he turns over in the middle of the night either. Even the one night the mattress pad didn't make it into the dryer in time for bed I did notice the difference the mattress pad makes in not making this mattress feel as firm, but it was still quite comfortable, just not as comfortable. I have no complaints. There were no smells with ours to start with so that never was a problem and it's still at a full 12" evenly across. I'm in the camp of those who were really skeptical of buying a mattress online. Especially a foam one since I've had a regular pillow top one for the past 10 years. Yes it was time for a new mattress! I had been shopping around for a new mattress for a few months trying out different ones, getting pricing and trying to make a decision which is kind of a big deal when you're more than likely looking at spending a lot of money. A friend suggested we consider the foam mattresses and that Amazon had some good prices on them. I headed to a local store to give their version of these mattresses a try and I was surprised how comfortable they were. After testing them out I decided to see what Amazon reviews had to say about the ones they offered. I read through the good and the not so good and the flat out bad reviews and decided to take a chance and see what arrived. I am super happy I did! Granted it's only been 2 weeks but so far we love this mattress! I had read the multiple reviews saying theirs didn't inflate correctly, had a foul odor, was lumpy, etc....thankfully none of that was true of what we received. To break it down..... cons... It is a firm mattress no doubt. I am someone who likes to pretty much sleep in a cloud and am a side sleeper so it's taken some getting used to. Since the cost of this mattress was so good I went ahead and ordered a high quality mattress cover/pad and for me it's really helped make adjusting going from a plush pillow top to a firm bed a lot easier. Going from a spring mattress to a foam ones takes some adjustment on the support on the sides. Obviously the spring ones tend to have more of a frame around the edges so sitting on the side of the bed is different. I wouldn't say it's bad but it's not as supportive. We will probably need to get a new bed frame here sometime soon. While the box springs we had from our old king are still in great shape the lighter weight mattress tends to slide and needs to be shoved back into place every night before going to bed. Not really any fault of the mattress it's just a con that I'll need to replace the bed itself in order to stop this from happening. Another con that's not the fault of the mattress it's just my bad luck....I missed where this was on sale just after Thanksgiving because I was still pondering what kind of mattress to get. So I paid the higher, yet still on sale, price. 4 days later it went back on sale again and has remained $40 cheaper for over a week now. Bummer for me, but still a good deal, just not as good of a deal as if I'd waited 4 more days to decide. On to the good stuff Pros..... Per my experience I say buy this mattress. Don't wait, grab it at the price it is now. I did not notice any sort of foul odor but I did open the windows and had the ceiling fan going while it inflated. It inflated to the full 12" and did so within an hour. We were sleeping on the mattress withing 4 hours of setting it up. It fit where our old king size was perfectly with no overhang or shortages size wise. It's around 2" taller than our old mattress so that took a little getting used to but it measured 12" with a regular school ruler. It was well packaged and fully deflated ready to go when it arrived. I'm a big girl and my husband is a fairly big guy and we both sleep comfortably on this mattress with our 3 large breed bed hogging dogs. When my husband moves at night he does so like a fish out of water and I have noticed he doesn't wake me up turning over because it's not bouncing me around like our old mattress did. I don't even really notice a dog moving around to a different spot. I'm a side sleeper who would love to sleep in a cloud so this did take some getting used to but it's never been uncomfortable. The first night getting to sleep and finding a comfortable position took a little bit but I could instantly feel I was better supported and my hip and shoulder didn't have the pressure it normally would. When I turned onto my back I felt almost like I was sleeping in a hammock. Not totally of course but the extra support was there where it hadn't been before. With what I saved on the mattress I went ahead and bought a nice mattress pad/cover to put on top to make it a little more soft. I had always been told you can make a firm mattress more soft but you can't make a soft mattress more firm so if it's too firm invest in a good pad and it can make a lot of difference if you prefer a softer bed. What I noticed right away is when I woke up I wasn't as sore. I feel a lot more rested in the morning and I'm not waking up to turn over or move around near as much as I was. Granted our old mattress was 10 years old and that had a lot to do with it, but still this mattress is obviously better and keeps me in a deep sleep for longer periods throughout the night. My husband also says he's sleeping better and isn't flopping around like he had been doing with the old mattress. He's the one of us always complaining about being hot while sleeping and he said he hasn't noticed this mattress makes that any worse, and if anything since he's not moving around so much it's better. We like it so much we plan to order the 8" version for our kid's bunk bed here soon. As we get more use of out this I will try to update this review for how it's holding up. I don't expect to get 10 years out of it, granted i probably shouldn't have tried to get 10 years out of the older one but it held up for at least 8-9 of those years. For this price I'd be happy if it lasts a couple of years. If it lasts longer even better. I highly suggest if this is too firm for you to buy a nice mattress pad and to buy it while it's at the price it is now. ... show more
