HERE IS ONE OF THE MOST IN DETAIL BRUTALLY HONEST REVIEWS YOU WILL READ. I'm a 16 y/o girl who bought this mattress for my room makeover. The price is totally unbeatable and I thought well, I'll just go for it. Here's my full breakdown and opinion on anything you could worry about for a mattress: THE COMFORT LEVEL: 10/10 I may be 16 years old, but I have bad scoliosis that affects my whole body. So I still get knee pain, all that fun stuff. Before I had opened the box and set up this mattress, I had also gotten into a bad car accident that hurt my lower back even more to the point I couldn't walk. At this point in my life, comfort is my holy grail. As a growing teenager, I needed to count on something that I could also sleep on for 12 hours and wake up feeling like I could take on the world! And this my friends, THIS is it! The comfort is amazing. My back doesn't hurt at all when sleeping on it to this day, even compared to my previous expensive serta mattress. I know a lot of people worry about it sinking over time. I weigh 105lbs but there are absolutely no signs of sinking no matter how long I lay on this bed. Also, it isn't super squishy. The perfect amount of plush with a hint of firm so you aren't sinking to the pits of memory foam. THE SIZE: 10/10 When I cracked this baby open, it immediately popped up. I didn't even wait the full 24 hours before laying on it because it immediately grew to it size! I even measured the corners! HECK YEA! CLEANING IT: 9/10 Don't know what the fake zipper is about on this mattress, but this baby is so easy to clean. MY SISTER POURED CRANBERRY JUICE ALL OVER MY MATTRESS! And as I was cursing her out and shaking my fists to the heavens asking "Why me!", sad that my brand new mattress could potentially be soiled forever, it was all okay after I grabbed some odoban!! I cleaned that sucker to the gods and now there is not a single stain!! Make sure you dab people and HARD! You can even rub it, it'll come out. And then I did what a smart human would do, put a mattress cover on. THINGS THAT BOTHERED ME: 1. I don't know if it is just me but....PREPARE FOR THE SMELL! It doesn't smell like green tea nooooo definitely not sis. This smells exotic. Not my favorite smell it was definitely a strange smell that I can't even identify. BUT THAT SMELT WEIRD! And I'll be honest...it took 3 weeks for me to not smell it. It was such a strong smell that I just made my bed and didn't sleep on it for a while. It made my sheets smell too at one point. Then I got used to the smell and just decided to kick it in my bed because I was tired of sleeping on the couch as soon as the smell died down. But by the next month, I no longer smelt it. I'll list below how I managed to get rid of the smell. BUT! If you are patient like me and are willing to pull through because it is a TOTAL pain in the butt to send a mattress back, then don't fret! It does go away and you will love the mattress after! Its been 3 months that I've had it and I've had multiple people do a smell test, the smell has vanished. I still think the mattress is worth it! HOW TO REMOVE THE SMELL: -Don't use too much febreeze. It'll be a temporary assistant, but honey it isn't worth it to drench the bed in more chemicals making the bed come up with more of a foreign smell. -I put scent soaking rocks in my room. You can buy these at home depot, they take away any weird scents. You can also purchase a air cleansing machine, NOT a dehumidifier. I don't know exactly what these things are called but my boss has one and they work great. You can get these for cheap at walmart. -Air fresheners for the car. A canned air freshener will definitely get rid of the smell but they are very strong. I just got some plain smelling glade air fresheners and put them under my mattress. This made my mattress smell like fresh linen by the second day. -Wait that sucker out! It's not too bad! 2. The heat, at first My mom just looooooooves to keep our house at 69 degrees making me a living ice cube. Therefore, I keep my vents closed. But, this bed will get you pretty hot sometimes. It could just be because of my comforter, but I never sweat and sometimes I will wake up sweating on this bed. This isn't an extremely justifiable complaint because it could be any other factor, but rest assured my vents are open fully because I do not want to smell like sweat! OVERALL.....This is a definite cop, not drop! Go ahead and buy this bed. If you are extremely picky, this bed is great to have in a guest room or maybe if you own airbnb's. They're cheap and comfortable and great as long as it air's out. I love my bed so much to a point that I don't wake up for days now!

Sooo happy with this mattress! I have now had this mattress for close to two years and I have been beyond happy with it. Here are some personal thoughts on it. Softness: It’s somewhere in the middle when it comes to softness. I have had really soft mattresses in the past and getting used to this one did take a bit of time, but it is so comfortable for my back and I never wake up with pain. Durability: It has held up perfectly these past two years. At about one year in I flipped the mattress over just to even out the time spent on each side, but I don’t think me doing that would’ve made much of a difference honestly. There are no sunken in spots left in the mattress between two people using it every night. Pressure support: It sinks in at all the right spots when I lay on it, and it makes all of my body feel supported. Cooling effect: I feel like the only thing I can’t really say much on is the cooling effect as I think it is probably lacking. Although, I’m not a hot sleeper, and neither is my partner, and I personally have had no issues with it getting too hot. Motion isolation: I get up so many times at night (always have been that way) and I never wake my boyfriend up from movement in the mattress. My main original buying reasons when I got this was the desire for something relatively inexpensive, and I didn’t want a mattress with fiberglass. It held up to both expectations and more!

I now own three of these mattresses, and that should tell you everything you need to know. This is hands-down the best mattress I’ve ever slept on — supportive, comfortable, and consistently high quality across all three. The medium firm feel strikes the perfect balance between cushioning and support, making it ideal for both back and side sleeping. One of the biggest selling points for me was that it's fiberglass-free and made with certified safe foams and fabric — peace of mind is a huge deal when it comes to something you spend a third of your life on. The zoned pressure relief is another standout feature. It genuinely helps reduce tension in key areas like shoulders and hips, and I wake up without the usual aches and pains. It arrived neatly boxed and expanded quickly with no lingering odors, and the setup was super easy. If you're on the fence, take the leap. I keep coming back for more — and I'm glad I did.
