Worth every penny! The topper is soft and smooth, the mattress is perfectly firm ( no hip pressure no neck crunch up) and it’s taller than I anticipated. Probably going to switch out all of our beds with this (over time). The box looked a little beat up but the mattress quality is perfect. No weird smells and or anything. Super easy to setup (unrolled it on the frame removed the plastic and within a few hours it was almost full size. It’s been a week now and it’s even more comfortable!

It is now January 30 2026, still sleeping wonderfully still have the topper on the matress and now that winter is hear I have my thicker blanket and I’m still sleeping comfortably and still not tossing and turning the only downside I have is that my topper slides off getting on and off my bed bc the mattress cover is slick and the topper is foam it tends to slide if you move not really the matress problem really just I need something that will give the foam topper a grip it will be fixed. Still very firm and even have a heated blanket on top and usually what happens is foam material as it warms up will loose some of its firm but this matress has kept its firm perfectly. Still highly recommend. And I am currently looking to get maybe two more different sizes for some others in my household! I got the twin size of this very firm 14” mattress and have been sleeping on it since October 23rd. After adding a 3” memory foam topper, it’s close to perfect. I sleep so well now that I don’t even toss and turn and wake up with no back pain. Supportive, cooling, and high-quality—highly recommend! I just received my new twin Firm-Gold mattress today and wanted to share my first impressions! For context, I’m 5’5” and close to 300 lbs, so I needed something supportive. My old mattress was a hand-me-down that had been used for years. Finding a good, affordable mattress felt impossible — like mattress stores think only the rich sleep! When it arrived I unboxed it outside on my porch (semi-closed in) and noticed no smell at all. It comes vacuum-sealed and had an extra layer of plastic — I saved that to use underneath for extra protection. I also bought a new box spring and deep cleaned my room while it decompressed. I read that firm memory foam can sag if not on a flat surface, so we cut some leftover plywood to size and put it on top of the box spring before setting the mattress down. After about 15 hours (it recommends 24, but I had nowhere else to sleep) I made the bed with Egyptian cotton sheets and my cooling blanket. The mattress itself has a built-in cooling effect, and with my blanket it felt cool and comfortable right away. When I first laid down it felt firm and supportive but still contoured to my body when I was on my side. I have chronic back pain, and surprisingly my back didn’t hurt at all — I wasn’t tossing and turning like usual. A big plus for me: the mattress has a removable cover so I can wash it — I wash everything for that fresh feel, so that feature is perfect. I also used zip ties to secure the metal frame to the box spring to prevent noise, and so far it’s totally silent. The only real issue was delivery: FedEx initially marked my property inaccessible (gate closed) even though my gate was open, my dog was secured, and I had family ready to help — my guess is the driver didn’t want to lift a 58 lb box. It was delivered the next day without issue. The bed sits a little lower than I’d like (14” mattress + 5” box spring on a short frame), but risers will fix that. Downsizing from a queen to a twin opened up my space nicely. Overall: very happy so far — firm, supportive, cool, and seems high quality. I’ll update this review in a few weeks about sagging or long-term back improvement

When I tell you that this mattress is EVERYTHING, I mean it's everything!!!. I truly have hip and back problems. I've had them for years. Years of injections, Chiropractic care, and pain meds. In 8 yrs I've purchased a Serta perfect sleep,(medium firm) 1,000 dollars and a Sterns and Foster (medium firm)1,800 dollars and would be in soooooo much pain in the morning. I've never purchased a memory foam mattress before. So in March my son purchased his 3 boys a Nectar medium firm memory foam mattress from Amazon. I sat on one and thought wow, this would be great if it was more firm. I saw Nectar Medium firm mattresses at Sam's but not firm... Since Amazon had Amazon days on October 8-9, I started looking at mattresses since the prices were great. I've looked at sooooooo many then I ran across this mattress and it was 250.00 less than regularly priced. All the reviews, with the exception of one stated that it is FIRM, FIRM, and everyone LOVED it. I figured why not, 350.00 for a firm, copper gel mattress isn't that bad. I took a chance and bought it, and btw an additional 50.00 came off at the checkout. So 300.00. I ordered it on the 8th and it was supposed to be here on the 20th, 2 days later Fed Ex delivered it, Like WHAT!!!!???!!! I was super happy and excited to get it. The box was heavy, my son and grandkids brought it to the bedroom and it was packaged well. I've read it is best to open in a warm room, so I had the blinds open and the sun made my room warm. I opened it on the bed and within 10 mins it was full and exactly 14 inches It is FIRM FIRM....I have never in my life slept so good. Better than a hotel mattress. No indentations, it doesn't move when I get up, my 3 dogs jumped in and out and I didn't wake. I love the grey cover. It's well made, and hey, I'm at the change of life stage and I have NOT been hot at night, no back or hip pains in the morning, no waking in the middle of the night. To be honest, I've been sleeping in as late as two hours past the time I normally get up to let my dogs out. They have been barking to wake me up.. Hahaha... I am super happy, and satisfied with my purchase. I totally, and highly recommend this mattress..

Quick and efficient delivery by FedEx. Difficulty moving from the front door to the upstairs bedroom(its super heavy) Besides we ordered a FIRM KING. Easy unpacking. Seemed to expand quickly, 6-7 hours 12" in the center, 13" near corners, FIRM but Soft, The Perfect Comfort, As if it was made for GoldieLocks herself. We also saved $180.00!! The edges seem to be less sturdy than being completely on/in it, That is why I reserved a star 🌟, Gives off an unstable feel, Sort of a slide off instead of a sitting on the edge supported experience. No funny smell. Brand new. Overall, I'm extremely impressed for A Bed In A Box. 📦 I made this review prior to sleeping on it, I'll check back in, In a month or so to update if possible.
