Amazon Basics Hybrid Mattress - 12 Inch Queen Size, Medium Firm Memory Foam with Motion Isolation Springs - Perfect for Back Pain Relief & Couples Sharing Bed

I received this bed 7 days ago today, and I slept on it the first night. The first night, it felt pretty great. Firm but the top half inch maybe, is soft, so there's a bit of give. 7 days later, the firmness has definitely fully settled and let me tell you, the support is just amazing! I was having so much upper back pain and some lower back pain, but I have been waking up virtually pain free. There's some tension in my back because I'm still adjusting to something more firm, but it's not pain!The great thing about this matress is that my partner is 6'5" and I'm 5'0", so we have pretty different needs, but since the top on this matress has a bit of cushion, it's not leaving me with pressure point pain in the shoulder or hip like I was worried about. I tend to sleep on all sides (back, stomach, sides lol) and so far I've slept comfortably every night. As for my partner, he says the matress is also very comfortable and has not been experiencing any pain. Neither one of us have anything negative to say about it. So, that's pretty good I'd say!Hopefully this matress will last a while and not cave in! I'll update this review in another 6 months or so. The more info the better, eh?So the mattress comes in a pretty big box. I got the cali-king 12" firm hybrid. Weighs about 100 pounds I'd say. The delivery man was a saint and brought the big ol thing right up to my apartment door. I thought they'd dump it just in the lobby.Opening it up was great it came in heavy duty plastic wrap so a safety cutter (or something without exposed sharp blades would work) cut through the plastic and the mattress !immediately! Started to puff up. The mattress was folded in half and then rolled up. Within maybe 3 minutes I had a fully puffed up 12 inch mattress in my living room. I am still going to give it the full 24 hours before sleeping on it but I did lay on it to test the firmness and it's really nice. As someone who works manual labor having that foam layer for comfort but the springs for support is just bliss.There's no weird smells or anything. The cloth is quite cool to the touch as stated in the listing. It really does look exactly like the photo in the listing too! Sometimes there's a little wiggle room for how things looks but this was to the tee. I will update after a night's sleep on it and try to update again later. Right now I'm just so happy to throw out my old mattress that's been ruining my sleep for the last 6 years!UPDATE: First night's sleep was lovely. It is firm! (I'm roughly 280lbs, hubbs is 220lbs) As a side sleeper I'm going to need a fluffier pillow. My body did not sink beyond the foam nicely contouring me. This mattress is very supportive. It is a bit bouncy though. If my hubbs moved on his side I did feel it on mine lightly. Nothing enough to wake me up but worth mentioning. The edges of the bed keep their shape however the corners have a bit less support. I don't see why anyone would be sitting only on a corner but they definitely condense far more than the actual sides.I look forward to many a night's sleep on this mattress!I got this mattress in hopes it would be a solid firm mattress with a very minimal amount of give but still comfortable. We got just that. This bed is the perfect firm mattress if you are looking for something that will keep its shape and only give slightly to your body weight this is the mattress for you. I saw a bunch of reviews saying this mattress was not firm enough or it didn’t fluff up fully. We let this bad boy air out for 72 hours (probably closer to 80 hours if I’m being honest) and that was the perfect amount of time because when we finally laid down it was just the right amount of firm and cushion. So to the reviews that said it didn’t fluff out reading is fundamental maybe follow the instructions because it worked great for usI like the design how it’s not just foam that sinks in!! And the coils add the extra support for a 190pounds person!! Honestly the hybrid bed is amazing, breathable once the plastic comes off!! Otherwise it gets a bit hot if the plastic is on and gives you night sweats.. it was a perfect fit for the frame I had!! That twin size is lightweight too!! Which is surprising!! Amazing upgrade from the foam bed I had where I use to just sink in.. the foam was amazing at relaxing though lol. Just sank in was my main reason to upgrade for better stability on the back support!! Easy to take naps or fall asleep at night!! Good recovery bed!!I am so happy I ordered this bed. It’s firm but still comfortable.. My other mattress was supposed to be a firm but sank when you laid in it. This bed by Amazon holds it shape and really helps with back pain. Really happy I bought thisI've been on this mattress for a month now and have no complaints. I was concerned that it may not be very good due to the price point but I've been pleasantly surprised. Both myself and the lady have been sleeping great and waking up with no pain. I will note that I don't consider it a "firm" mattress like it is listed as, more of a medium firm. I think it is due to sinking into the memory foam but there is plenty of support from the springs.I will update this review at the 6 month mark, 1 year, 2 year, or whenever it turns to crap so others can know what to expect from this.I searched for 3 months searching for a firm bed, even ordered a mobilly belt and bed and had to return it because it wa stop soft. BUT THIS BED HAS everything I been looking for. Good firmness with a slight sink. The sink is more like a hug to your body. The edge support is 4/5 could be a little better but I have absolutely no complaints. It’s true to size lines up perfectly with my bed frame. I’m 5’11 215 lbs and this bed feels amazing.Between the mattress and the packing, only a strong person or two weaker ones can unpack this mattress. I guess it's inevitable. The packing is now stacked on top of my dining table halfway to the chandelier. I suppose a trip to the dump is next.
