The FrankenBed
|
I initially called my creation the FrankenBed because it was made from "parts." The word is taking on a new meaning, as in, I am creating a monster. The basic outline was a latex core, an Intelli-Gel topper from MyComfort, and something in between, possibly 2" of Foamex memory foam. The first major piece to arrive (not counting the foundation on top of a set of Bed Beams), is the latex core. I'll get the Intelli-Gel topper on Monday or Tuesday. I think I might already have a problem. I ordered an ILD 40 Talatech blend core, and I don't think it's going to be firm enough. I initially ordered a 44 but then changed my mind and went with a 40. I should have stayed with the 44. The core actually tested out at an average ILD of 37.8, but I'm not claiming the 2 points is what makes it too soft. Even on 3 2.8" layers, I can bottom out by sitting down on it hard. It's sitting on a concrete floor covered with carpet and I can definitely feel the floor. At the very least, I need to replace one of the ILD 38 layers, and possibly both. I can't bottom out all 4 layers, but that's 11" of latex, and support-wise, it feels pretty soft. Laying on my back, it feels very firm, but it feels like my butt sinks down further than it should. In other words it's almost too soft AND too firm at the same time. Too soft for my butt but too firm for my shoulders. Y'all can go ahead and laugh at me now for thinking I could save money by building my own mattress. Not happenin'. The best that can be said is that maybe my own mistakes can benefit others. I'm debating on what to do. I can be stubborn and order another core, or I can just admit that I made a bad decision and order a support mattress from someone that allows comfort exchanges. I have to allow that even the 44 might not be firm enough, so a money back guarantee would be a good idea too, the second time around. I have some decisions to make.

What changes in your purchases would you make '20/20' ? Is the bed heavy with the comfort layer and the mattress core? What is [so far] sleep temp of that layer? With the slat foundation, what is the overall height? Will it fit a headboard? Are you still adjusting it? What pillow seems to work best with your bed so far ? Thanks for all the research time you've put in and posted information.. It will look like a typical mattress when I'm done. Right now it looks like the "prototype" that it is -- Eastern King Intelli-Gel topper sitting on top of naked Cal King latex cores, sitting on top the flexible slat foundation, sitting on the floor of my living room. Once I get a proper mattress cover and the right size Intelli-Gel topper, it will be pretty ordinary looking. This is an image from the Intelli-Gel website:  It is pretty heavy. The flexible slat foundation shipped in three boxes totaling 189 lbs. The Intelli-Gel topper weighs 150 lbs. The latex core weighs ~90 lbs. The total height of the final product will be 19 to 20 inches:
I am still working on it, but I'm pretty close. The "zoning" of the flexible slat foundation has my spine in pretty good alignment, but the Intelli-Gel sitting directly on the ILD 38 latex is a skosh too firm, so I'm contemplating 2" of either memory foam or latex as the top layer of the support mattress. The only pillow I have slept with so far is a Tempur-Pedic body pillow. I sleep on my side and I'm a pillow hugger. I have a RejuveNite (Latex International) shredded latex and down pillow coming Real Soon Now. This message was modified Sep 30, 2007 by haysdb

You mentioned to get more of the full 'slat' feeling, a thinner core mattress could be used. Based on your recent discoveries and experience. You would still buy the adjustable slat foundation, mycomfort gel layer, but a thinner core mattress [med or firm?], with a HR foam layer UNDER the gel, but above the core mattress? You seem very close at this point, once it 'fits' a zippered mattress cover will enclose it all. Will you need deep pocket sheets? I think reg is up to 10 inches, deep is up to 15', and very deep up to 18-20', depending on brand. I did not get any feet with my foundation. I did not request any. I upgraded my bed frame to a set of 3 "Bed Beams" which will support the weight of an elephant. However, since the flexible slat foundation is comprised of three sections bolted together, and because the Bed Beams do not provide the recommended center support running head to foot, and because FloBeds recommends 5 slats, two under each head and foot sections, I may add back the two original cross supports I replaced to bring the total to 5. That seems like massive overkill, but they are just going in the trash otherwise so I might as well use them. I definitely like the flexible slat foundation, and I'm pretty sure I'm going to like the Intelli-Gel topper once I get the right amount of cush underneath. The support mattress could be anything. MyComfort sells innerspring, air and memory foam support mattresses that are specifically designed to be used under their Intelli-Gel overlays. I'm doing latex because I liked the feel of Intelli-Bed's $4000 latex mattress. You could do all Pulyurethane, with maybe a layer of HR, or even the more conventional 2.2 or 1.8 lb foam, on the very bottom for the support core and then something like 4 lb Energia (ILD 27), or memory foam, under the overlay. I can't begin to recommend any one of these over another because I haven't tried them all, and you might like something different anyway. The total thickness of the two "mattress" layers will be ~13". My current sheets will fit, but there is no way my fitted sheets will tuck in along the sides because they don't already and my current mattress is only 12" thick, so I will probably buy a couple of deeper fitted sheets.

Intelli-Gel overlay
|
This ties in with information in this thread, but is here because it specifically relates to the queer way that I'm using my Intelli-Gel "comfort overlay." And before anyone goes off on me, I am not asserting that my creation is superior to an Intelli-Bed or MyComfort mattress. It's just different, OK? The thing I was most interested in was what was attached to what inside the ticking.
I bought the Intelli-Gel overlay hoping to incorporate the Intelli-Gel into my mattress, as just another layer of "stuff" zipped inside a cover. My idea was that when you looked at my mattress, you would see just that - a mattress, and not layers of foam with a skinny mattress stacked on top. Having the Intelli-Gel be a separate "mattress" DOES have it's advantages, namely that a King-size topper weighs 150 lbs. You heard me right. Stack that on top of 90 to 135 lbs of latex, and you have a heavy mattress that would NOT be fun to move as a single mattress. The Intelli-Gel could be removed from the zippered cover for transport, but then you have the very real concern of damaging the foam under and around the Intelli-Gel. But the bottom line is it would easy to slide the Intelli-Gel out of the nice stretch knit topper and lay it right on top of a layer of latex inside a zippered cover. And that's the direction I'm heading.

I think the Intelli-Gel topper needs some additional inches of "comfort layer" between it and the support core for a side sleeper. I have slept four nights now on the Intelli-Gel placed directly over an ILD 38 core, and have experienced some numbness in the arm I'm laying on. I have been debating over what to use. There are at least 8 companies selling a 2" latex topper [1], but only two in anything above a "soft" (22 ILD or less). Since this is a "middle" layer rather than the top-most layer, I think a soft would just be too soft. I ordered a 2" layer of ILD 32 talalay from Foam By Mail. They have a satisfaction guarantee in the event it's too firm. I have found no one selling an ILD 28 topper, so if the 32 is too firm, the next step will have to be a 24. [1] Foam Source, Foam By Mail, Absolute Comfort on Sale, Faom Online, Foam Order, Memory Foam, Sleep Warehouse, and Mattresses.net all offer 2" latex toppers.

Re: The FrankenBed

The 2" ILD 32 latex topper arrived today. My first thought when comparing it to the ILD 38 layers I have is that it was not going to be enough softer to notice, but it is. The feel of the mattress is still "firm" but I experience more of a floating feeling now when I lay on my side. The next step down from the 32 is a 24, as I have never come across an ILD 28 latex topper. My concern, as before, is that would just be too soft, but maybe it wouldn't be as long as the core was properly supportive. In my case along with the slightly more conforming 2" topper is the return of the sinking hips feeling. As I soften up the top, I need to firm up the support layers, so I have asked Dewey if he will sell me an ILD 44 to try. I might also ask Shawn at SleepEZ if he has an ILD 44 dunlop core. If dunlop truly has a higher support factor (something I have never been able to confirm, but it makes sense that it would), then it would be ideally suited to a bottom layer application. I am also anxious to experience the difference between talalay and dunlop first hand. I am really close. I could be very happy with what I have now. I have been sleeping on just the Intelli-Gel over the ILD 38 core for two weeks, and could have lived with that. I have been sleeping through the night and not waking up with any significant aches or pains. But "good enough" isn't why I started this journey, so the quest for "perfection" continues. Interestingly the question of whether 1" of latex or memory foam would make any significant difference arises. I feel like I'm close, really close, and I'm looking for only a very subtle increase in softness. This may be where I get to throw a bit of memory foam into the mix. Conventional wisdom aside, not all memory foam needs body heat. And for this reason, does not have to be used as the top layer in a mattress. I visited a Verlo mattress factory a couple of weeks ago and they use a 1" layer of memory foam between two 1.5" layers of latex in one of their mattresses.

Re: The FrankenBed
| That 1" 20 ILD FoamByMail has tempted me. I also wonder if 1" would do much. I wish they had a 1.5". |
Re: The FrankenBed

Re: The FrankenBed

I have been sleeping on the 2" of ILD 32 under the Intelli-Gel topper for a few days now and it's just not conforming enough. Support is fine, no issues there. The thing about the Intelli-Gel is that it is actually very firm in areas where there isn't enough localized pressure to collapse the columns, so it needs something soft under it. That's my working theory anyway. The $64,000 question is how much and of what. The next step down from ILD 32, that I can get at a reasonable price, is ILD 20. MyComfort uses 2.8" of this soft latex in their Single-Gel with latex, so maybe I shouldn't be so "afraid" of it. OTOH Intell-Bed's latex mattress is too soft, so I know it's possible to go too far in that direction. FoamByMail offers 1" talalay, so that's where I think I'm heading. It's what I should have done the first time. 1" of 32 and 1" of 20 would have given me two choices of firmness between 32 which I figured would probably be too firm, and 20 which I figured would be too soft. I could have added one more layer to fine-tune and gotten it exactly right without having to return anything. |
Re: The FrankenBed

My new toppers arrived today. Rather than just piling them on top of the stack, I pulled out one of the two layers of ILD 40, leaving the 2" of ILD 32, and added the two 1" toppers. One was supposed to be a 32 and the other a 20, but they feel the same to me, both soft, so it looks like they sent me two layers of 20. That's OK. The net effect is I should have softened up my mattress by a LOT. I want to feel what too soft feels like, then I can firm things back up if need be. I'm trying to keep the mattress to about 12", which gives me up to 8" of latex plus 4" of Intelli-Gel topper and quilted mattress cover. 2.0" 32 --> 2.0" 20 2.8" 40 --> 2.0" 32 2.8" 40 --> 2.8" 40 --------- --------- 7.6" 6.8" There are several other combinations I can try if this is too soft, including:

Re: The FrankenBed
I am now committed to a mattress cover for everything, so I know what I have left to play with in terms of foam layers. I am going to remove the Intelli-Gel overlay from its cover and put it inside the same cover as everything else. This gives me a cover with wool quilted into the cover rather than foam, which might help it sleep a little cooler, and it gets rid of the vinyl layer under the Intelli-Gel. Right or wrong, I just don't like that sheet of plastic in my mattress. I suspect one reason they used vinyl is because of the weight of the Intelli-Gel, which is around 150 lbs for my Cal King. This could pose a problem for me in handling the Intelli-Gel outside the cover, but I'll just have to deal with that.
I'm told I can fit a maximum of 12" of foam inside my new cover, so I have up to 3" available to play with between the support core and the Intelli-Gel overlay. And herein lies my current dillema. I have two 1" layers of (ostensibly) ILD 20 latex. I would like a bit more cushion. The following options are under consideration:
I am leaning toward 2" of memory foam from a company offering at least a 30-day comfort guarantee. After all, I don't know if I will even like it. FoamByMail is the least expensive "good" 5# foam I am aware of, but I sure do like the Foamex memory foams. But since this is an "inner layer" of the mattress, it's hard to justify the higher cost for the incremental increase in quality. This message was modified Oct 26, 2007 by haysdb
