There is no kind way to start this review so I'm just going to be blunt because you deserve blunt in mattress buying - it is SO important to be clear because a good/bad mattress GREATLY impacts your life! So here we go with the blunt - are you ready?! We're short, fat people. No. Really! About 100lbs overweight each. Don't judge - we have our reasons & I'm not sharing to open myself up to ridicule + with the New Year we are committed to losing! So why do you need to know we're fat, short people?! So you will know that because of our sizes we have really put this mattress through a workout since we bought it in August...and it is FABULOUS!!! I'm a side then move to back sleeper & my husband is a back sleeper & we both sleep like the dead in this bed! The bed is NOT hot, when we climb in (hello- we're short gotta climb!) we can tell there are springs, but when we lay down we don't feel them (no poking, etc.), and overall our bodies just feel well supported in a not too firm way! To think we bought this as a temporary bed - just to have since we moved 2200 miles & weren't taking our old mattress with us. We figured after we found a house to buy we'd upgrade - found the house faster than we planned & now this bed is coming from our temporary apartment to our house!!! With the outlay of so much money updating the house it's nice to not have to invest in a new bed! Just to give you a comparison - previously we had the Lucid 10" (https://www.amazon.com/gp/product/B00478U768/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) which at the time we spent $349 on & is now priced at $287 as it should rightfully be priced less than this bed because the Lucid SUCKED! It was comfortable for about the first 6 months & then it started forming a divot in the shape of our bodies & gotta say - even when you are the person making the divot you still don't want a fat person divot in your bed! The Lucid was also REALLY hot - we would sweat on a winter's night while it was raining outside & the inside of our house was never warmed to more than 68°F! The divot also affected smoochy-smoochy time (divots are REALLY not conducive to that!). We kept the Lucid for about 18 months after we were both disgruntled with it because we knew we were moving & wanted to move small. For the last 6 months I didn't even sleep with my husband. I slept in this recliner (https://www.amazon.com/gp/product/B002WGJHHW/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) in the living room & got WAY better sleep in a cheapo (yet fabulous) recliner that's NOT made for fat people than I ever did in the Lucid! Bottomline - this fat lady has sung! Mattress buying is over! If we need another mattress at some point we'll be buying this one again! Already decided to buy the Queen size for our guest room & the 8" Twin for our children! I feel like Oprah - guests get a Zinus, children get a Zinus, everyone (in our family) gets a Zinus! Now that you're done reading my review - YOU go get yourself a Zinus!!!

This mattress has stood the test of time!!! I've had it since 2017 and it's still firm and strong like the day I bought it. :0 I never really considered how well it's been doing until now that I'm forced to buy a new one and not because it finally gave out. Oh no. Rather... because my brother's girlfriend's cat decided to use it as a litter box while I was at work... -_- Unfortunately cat urine never truly comes out of anything so now I have to depart from my precious sleepy time partner. DX In summary. Mattress > Time, use and abuse Cat > Mattress Me = :,(

On 9/18/2023 I got rid of my 20 year old, lumpy mattress. I am no longer sleepless in Lincoln, Nebraska. My new Zinus mattress in a box is surprisingly quite comfortable. Medium firm. Not too soft - thanks to innerspring. Not too firm because of the memory foam & cushionioning. This mattress-in-a-box exceeds my expectations for an economy mattress. Good value. I am pleased that I chose this, especially because I just read an article that stated that anyone who has back pain or stiffness when waking should NOT buy a FIRM mattress. We should buy a MEDIUM-FIRM mattress -as I did.

Ordered for my son’s bed. He loves it! He says it’s really comfy. I did lay on it too and I love that you don’t just sink into it. He has a box bed and it’s thick enough to go higher than the sides, which was one of our bigger concerns. It is a really snug fit too. If you also have a twin size box bed, it’s not going to leave any kind of gap.

We needed a new mattress for a FULL size bed. My son suggested looking on Amazon! I asked "for a mattress?"! He said : "yes Mom"!! So, I did, and we are very happy with it. It is very comfortable and no back pain getting up in the morning. I also have to commend Amazon, the man who delivered it was an Angel! We are senior citizens and worried how we would get it in the house, well, this man just put it up on his shoulders and insisted he was bringing it in for us and he carried it down to the room, we were thrilled and relieved. No UPS man has ever shown that kind of consideration or thoughtfulness. Amazon is great!!!
