Review: Very Good Support - This review is for the 8in mattress. Nice and firm mattress. I'm 6'4, 275lbs and this mattress offers good support and comfort from head to toe. I have it set up on a simple metal base and the feel is firm/extra firm imo. At least in the 8in version. Even at my size and weight I do not sink into this mattress, there is no sagging, and its easy to move about on. You truly sleep atop this mattress and not in it, so to speak. The padding is responsive, the springs feel strong, it feels quality so far as a bed in a box is concerned. Very satisfied with this purchase and if in want of a FIRM mattress this may be for you. YMMV, of course. What is firm for me may be less so for some, too firm for others. But for me its excellent. Oh, and that includes very good edge support. Lay at the edge, sit at the edge, whatever. It will not collapse, you won't go rolling off. Exceedingly happy with this mattress.
Review: I'm a side then move to back sleeper & my husband is a back sleeper & we both sleep like the dead in this bed - 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.desertcart.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.desertcart.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!!!
