Making adjustments to my latex mattress

Thank you! I'd like to start a new thread called "reviving a warped latex mattress?"

The 2 longways support slats in the Zenhaven foundation pushed the sides of the bed up and allowed the middle to sag, so there's a bit of a taco bed effect.

I thought with how resilient latex is, it would go flat when I put it on the floor. Nope. Even though I sleep on one side of it (and have ONLY slept on one side of it), each side has a little roll sensation towards the middle, which is visibly lower. I've never even slept in the middle.

Is there any way to flatten it out? I'm not strong enough to flip it, which I think might help, but might be able to get help this weekend. But I'm wondering if it CAN flatten back out...not sure why it's maintaining this shape.

Hey sweetandsourkiwi,

What size is your mattress? I will get a similar general thread started. It's surprising to have the latex to have such a drop in the middle of the mattress. Most times the dips or compressed parts are usually lost height well before the actual rubber loses any noticeable height.

With king size all talalay mattresses, there is a seam in the middle of the mattress, most times, as Talalay is only made in Twin XL and Queen size molds, so all kings are two TXL glued together. Sometimes that seam may have operator error os some issue causing the glue seam to be weak, thus creating a seam/space between the two Twin size cores.

Thanks,
Sensei

It's a queen. There are seams, but ironically they are where the mattress is higher, because they are 1/3 of the way in on one side. I'm not sure what the issue is, maybe the cover has somehow shifted around and is holding it in that position. I tried to shake it out and minimized it slightly, but there is still a slight sensation of not being totally flat. It is minor now but you can feel it. I don't see how to attach a photo anymore, but I'd say it's visually about a quarter inch of saggage under a yardstick placed across the bed. No saggage head to toe. I'm wondering how much I should let this be a deciding factor.

Hi sweetandsourkiwi,

Yeah, could be the foundation caused the cover to bind the latex into that shape. Perhaps you could get help to flip it over and then lift up on the sides a few times and see if the dip remains when you flip it back. Not sure I'd bother until you get your new foundation though.

Thank you! Reporting back on the difference between floor, foundation, and slatted frame (I didn't actually sleep on it on the frame, though...just tested for a brief moment to see, since that configuration is verboten.)

I will have to come back to the foundation in my final Zenhaven report, which I plan to share with the company. Short story, their bed is *significantly* comfier on anything else, and that foundation is costing them. Wish I'd discovered that sooner!

The floor wound up being lovely, a nice "damp" feel. Like sleeping in cashmere sweaters, kind of. Overall, it felt a lot softer and the shoulder pressure improved (didn't disappear, though.) I did start to get low back pain though, so it may have just proved too soft overall with my topper. The mattress on the floor was unfortunately not soft enough to use with out the topper.

The quick test on the slats confirmed why the bed doesn't belong there. The lower, softer layer just gets unevenly compressed and poofs out a little between the slats; it makes the bed feel thinner and firmer. It brings back some of the rebound and liveliness that goes away on the floor, and that didn't feel pleasant to me. I think the slatted frame would work a lot better with a latex bed with a firmer bottom layer and maybe a firm cover on the bottom to prevent any squeeze-through.

Now that the Zenhaven is back on the foundation (awaiting return), I have shored up the less supportive parts with folded wool blankets. Amazing how much you can affect a "zoning" feel with just a little bit of blanket under the mattress! It reduces pressure in my shoulders and hips too. Just crazy to me how much these subtle changes really affect the feel overall.

I do wonder if some jury-rigged "zoning" might help you in your quest, @Lotus14...maybe a towel somewhere in the layers or under the mattress, under the lumbar would lift you up a bit overall? It reduced my shoulder and hip pressure a lot last night. I wish I'd uncovered this trick sooner. Zoning doesn't have to be this expensive manufactured thing...you can test out some with zero commitment with just a blanket or towel. At least on these flexible latex mattresses, they really respond and conform around it. Who knew?

Well, I certainly didn't know! lol.

I didn't like the idea of plywood under part of my mattress. But a folded blanket or something in just the right spot might help prevent cratering on a very plush build. Thanks!

Hey sweetandsourkiwi,

I changed the thread to a more general thread about latex mattresses. Really nice information in the summary of the different foundations and how they affect the Zenhaven.

I can see your point about the soft side puffing out between the slats, one of the things I hadn't thought about with the two-sided feel. I am a bit on the old school side and prefer latex mattress firmer always on the bottom for support, progressive construction, etc etc.

And as @lotus14 pointed about the towels and/or something else for support...sometimes it is the simplest creative ideas that make so much sense. And of course, manufacturers know that some sort of "zoning" is helpful as many consumers have said this over the years...so they do what they know how to do.... try to develop products that are supportive and maybe getting to people's ideal spinal alignment balance.

Regarding the seams being higher, this is probably more common actually...and it makes total sense it being 1/3 rd of the way in. They need to use 1.5 TXL cores to make a queen - 40 inch width, plus 20 inch half core = 60 inches width = queen size. Zoned cores were produced in TXL molds.

Thanks,
Sensei
