Hi Largefarva
I'm also in the market for a new bed and have been looking at the Winkbed, as well as forums for advice. I'm sort of near your body specs (6'0" Male ~210 lbs back/side sleeper). From what I've gathered about Winkbed hybrid reviews, a lot of the negative feedback regarding durability came from several years ago, where some users on here commented their mattresses used 1.5lb/cubic foot foam in several layers, which caused it to break down fairly quickly, despite being very comfortable. More recent reviews, however, say the company uses 1.8lb in both the soft and LF models (this was one review from someone who only posted that one comment in a thread in which someone else was told the foams were "between 1.5-2.0 lb, which isn't encouraging), but recent reviews also state the mattresses are hideously uncomfortable and entirely too stiff. Maybe this has to do with the change in foam types done to address durability issues, if indeed there was a change (their warranty did change around mid-2018 to only cover mattresses purchased after that date, so maybe there was a change in materials, maybe not). Either way, I'm not thinking the 2" of 1.8lb poly is ideal for heavier body types, and if lighter people are complaining about the poor pressure relief of the Lux Firm, I don't know what your experience will be with those springs sitting two inches below the surface. Have you looked at Bear Hybrid? Little softer but supposedly with good support from the deeper springs. They're not zoned, but it's a consideration. Same with Nest Alexander Hybrid, and with that one you get a zipper so you can flip/rotate the comfort layers, extending their life and allowing you to buy a new pad (I'm sure at great expense) when the time comes. I hear those wear out in about a year, which is unfortunate, though these people admitted they did not rotate their pads, and people who did rotate them say they lasted longer than that, about 3 years before needing replacement (though these were mostly average sized users on their medium, which is really soft, whereas you'll probably be going for firm, so who knows). It's eh, but at least you have an opportunity to save a little money, if only through spending more? It is, after all, America. If you don't want to deal with all that, you might consider latex. I’m not sure your price range or feelings about latex, but I can recommend my own setup, or at least a better version of it: You could shoot for a Talalay latex (~20-28ILD)-on latex (~40ILD)-on-springs setup, so you get the vertical “soft” real estate plus spring/latex support without bottoming out on the springs. I've had mine for nearly four years and there is a noticeable depression, but I also bought an inexpensive mattress with soft microcoils instead of a second latex layer, so that along with my rather prodigious rear-end likely had a good deal to do with it. Winkbeds has the Ecocloud, which costs a little more than the hybrid, but has more (IMO) legitimate support from the community than their flagship hybrid model, especially with regards to durability. If it's not supportive enough with a single layer of latex, even at a generous 4", you can order a topper from Foamorder, or even an entire latex mattress. Their prices are pretty good, though their mattresses are on the expensive side and don't really have a "premium" vibe, if that's something you care about.
Regarding other reviews for Winkbed, I think I know the reviewer you're talking about, who says his soft version from 2016 has held up perfectly. He has the karate picture, right? I don't think he has the hybrid. I think he has the Ecocloud, but I might be wrong.
Regarding some of the other positive reviews: In a more desperate time in my life, I worked in advertising, specifically guerilla web advertising. Some of these reviews contain the kind of language and structure we were instructed to use to create compelling fake posts on message boards. Specific details about fabricated family members, exclamatory statements, positive claims about one commonly negative-reviewed feature of the product, especially in a thread that is skewing away from the company's favor, and a loosely “narrative” tone e.g. “I bought this mattress in ______ and it’s been the best sleep of my life. My husband doesn't complain about back problems anymore and the mattress is just like new!”. Again, not a proud time in my life, but now I have a nose for it and some of these posts smell funny. A bubbly mother-of-two-and-half making her first post in the middle of a negative mattress message board thread and then disappearing? What’s her motivation for being here? I mean no offense at all to other members here who are legitimate mattress enthusiasts or who truly endorse a product, but these are first posts. What's not happening in her life that brought her here on a random Wednesday five months after her purchase? That's almost always an English major at NYU paying for books at five cents a word, or an employee/manager/manager's spouse at the company with a passive search enabled. People don't tend to go on message boards to comment about products with which they are satisfied and purchased a long time ago, unless they are making their own threads because they are so happy they want to share their experience with the community, and even then you mostly see those with new-new purchases. People come here because they want information, or they want to complain. In this vein, we might consider that the Amazon reviews for the Winkbed were guerilla advertising as well, only of the "take-down" variety. Or, and I think this is more likely, it might be that Winkbeds stopped selling on Amazon due to negative feedback over which they had little control, as opposed to their own website and from sponsored Youtube reviewers. The mattress is no longer available and Winkbeds no longer has a storefront on the site, though they did at one time, as can be seen in the “answered questions” portion of the page. Why take it down? Other than the reduction in overhead from paying Amazon per purchase, why remove their presence on the site? Other companies seem to do just fine still selling through their marketplace, if only for exposure. But then why not also take down the product with so many bad reviews? Mysteries abound.
In any case, it doesn’t look good for Winkbeds. The real takeaway though is that it's great to live in a society in which it's nearly impossible to tell if someone is trying to help you, soft-arm rob you, or sabotage their betters on the marketplace at your expense. Again, not a proud time in my life and maybe I'm projecting a tad. After I find a mattress, maybe I'll get fitted for a foil hat and start sending out apology letters to the people I've “guided” toward buying inferior products. I also don't want this admission of my own past moral turpitude to reflect poorly on the mattresses I've recommended. Nest and Bear and Foamorder and certainly Winkbeds are not paying me, I'm just considering your body type and sleep position. Of all of them, the Bear hybrid seems to offer the most for larger people, who seem to swear by it, and pressure map tests (however much from paid reviewers) tend to support these claims, though again I can't speak to the durability of their foams, and they are not replaceable unless you want to take an X-ACTO knife to the case and void your warranty.
Best of luck on your mattress shopping journey. Hope Mordor treats you right, I'm already feeling a little burned. But TMU has really been the "Eagles" of this whole experience. Great community and Admins.
