I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| I say hybrid because I artfully combined 4 different materials with VERY different properties. Traditional poly foam, egg-crate poly foam, memory foam and wool. After months of trial and error, I found my dream mattress.---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Set DIRECTLY on the floor (for extra stability), I made an extra long twin mattress composed of the following: 12" thick poly foam with an IFD of 50 (very firm), topped by 4" of poly foam with an IFD of 35 (moderately firm) covered with 2" of 5.3lb/ft3 Sensus foam with an IFD of 15 (soft) topped off with 2" of egg-crate poly foam with an IFD of 35 (I found that by putting the traditional poly egg-crate OVER the memory foam undid that "squishy" feeling and and gave the mattress a nicely balanced responsiveness. I covered all that with a HEAVY weight (I think it weighs 60 lbs!) wool comforter (which gave it even more textural evenness), sealed it up with a clothed-vinyl mattress cover, added a fitted cotton mattress pad over THAT, added sheets and AHHHHHHHH. My perfect mattress. |

Where did you purchase the Sensus foam and how much was it? How do you know it's the real deal? Alice |

I will have to send you the details via pm as to not violate the forum rules. I'm not allowed to promote any website in the forum but I'll gladly send you all the links in the private message................................................................................... I know it's the real deal because it's got a density of exactly 5.3lb/ft3 (I made the measurements myself) It was purchased from an "A" rated BBB accredited site and it has the trademark pink color unique to Sensus.

| Pete, do you have any mattress / mattress component industry affiliations at all? If so, you probalby should disclose it. Other posters say all the time where they purchase things, but you don't seem to want to. Are we all breaking the Forum rules? |

I get it now; no SELF-promotion. I'd misunderstood - no promotion of any site at all! lol FYI, I have no affiliation with any mattress company et cetera. I'm a Pharmacist This message was modified Feb 5, 2010 by Pete

Layer one. I bought a 6" thick full sheet of Lux-HQ from foamdistributing.com I cut in half the long way and stacked them w/o glue. This made a 12 inch base for a extra long twin bed. This message was modified Feb 5, 2010 by Pete

Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| Layer 2: from foamdistributing.com a full sheet of HD36-HQ 2" I sliced it the long way and applied a VERY thin layer of spray glue to make a 4" thick extra long twin piece. |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| Layer 3 was 2" of Sensus from foamsource.com. I trimmed the excess length from the poly foam layers using an electric carving knife. Then (no glue!) I carefully aligned the sensus foam with the other layers |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| Thanks Pete. Frankly, I never even looked at the forum rules before. I think it okay to state where one purchased things or where someone could purchase things. If not, this site would not be that useful. Of course, any affiliations or conflicts should be disclosed. |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| Layer 4 was 2.5 inch HD36-regular eggcrate foam from foamdistributing.com I had to order a full sheet so I just cut it to fit. Lay it on top, no glue |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| Layer 5 was given to me by my grandmother. It was made in the 1950's and is a wool comforter that is king sized. It weighs 60 pounds! I wouldn't know how much one like that would cost today or even where to get one! I folded it in half the long way (after sending it to the cleaner's lol) and placed it on top of the eggcrate foam. This had the most wonderful effect of binding everything together! The mattress before had been just a bunch of separate layers but this heavyweight comforter seemed to make the mattress more than the sum of its parts! It was the missing link. |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| Layers 6 and 7 were simply to seal the mattress from the elements. Layer 6 was a cloth covered vinyl mattress cover. Layer 7 is an easy-wash cotton mattress pad. I love this bed and it frankly puts the BEST Tempurpedic to shame. All for around $700. |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| Another nice thing is, if one layer wears out I only have to replace that one layer, instead of buying a whole mattress!!! For example, after about 4 years, I found there were the beginnings of some hammocking, it was the eggcrate layer in need of replacement, after that everything's great! |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| How long have you been using this? The one issue with poly foam is that it may not last over time. Higher grade, higher density should last longer. I replace my mattress cushions with a high grade poly foam and it has lost its firmness over the years. |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?

After 6 years, The base layer (the most expensive layer) (LUX-HQ) is as if brand new. I can tell it's going to last for at least another decade or maybe even two. From time to time I disassemble the bed to inspect for signs of wear, I may have to replace the HD36-HQ in the next year or so, but at a cost of only $90. The Sensus layer has reach a steady-state softness with an ifd of about 12, now; it seems to be doing its job of acting as intermediary between poly and wool. About every 3 years I replace the eggcrate layer for around $25 (actually $50, but I only use half, I roll up the other half for the next time in plastic) All these foams are manufactured by Foamex Innovations, the world leader in foam technology. I think the thick, wool layer is protecting the poly foam, also, the mattress is tightly sealed with a cloth covered heavy gauge vinyl. This message was modified Feb 5, 2010 by Pete

Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| You say you cover it with a cloth vinyl? It has vinyl in it? It seems like that would not breath and be too hot. |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| Did I mention this whole mattress was about $700! Even if it only lasted for three years it would be worth it. Most beds you get at your basic furniture store give five years at best. And I bet for a whole lot more than $700! |

The mattress doesn't breathe at all. (internally that is) That's by design, it prevents oxidation of the poly foam, a major contributing factor to poly foam degradation. I want it hermetically sealed and it just about is. The very top layers, (which are in reality not parts of the mattress) the thick cotton mattress pad and sheets provide all the "breathe-ability I need. It's extremely comfortable.

My perfect mattress. Pete, I"m very happy for you; if it works for you that's all that matters. My only caution to others is that poly foam tends to die much quicker than latex. It appears your base layer is lasting and I am surprised and happy to hear that. And you're right, having it in layers makes it so you don't have to replace the whole thing at once. My experience with HR foam - which is supposed to be rated for 10 years - is this: the 1" layer I was using seemed to have given out on me. I can't prove it and I admit I could even be wrong, but it sure seems that when I replaced that layer, all is good with my mattress again. And I only had that layer in use for about 2 years. As for Sensus, some like it but to me, that also seems to give no support. (Could be too that my Sensus from Overstock.com is not really Sensus! ) I'm not knocking your accomplishment, nor your foam, I'm just saying to others, "your mileage may vary" with the poly foam. Thanks for reporting this, though; if I ever do a pure foam mattress again I will consider some of your info in this post, in my configuration! p.s. Are you serious?! A 60lb wool topper? Where the heck did you get that?! And how much did you pay for it! Wow, that's a lotta wool! (Or does it have lead sewn into it?!)  This message was modified Feb 6, 2010 by jimsocal

Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| HAHA, the wool "topper"is a dinosaur. It's a super thick wool comforter that was made just after 1950, my grandmother gave it to me. she'd kept it in a cedar chest practically covered in naphtha. I don't think "they make 'em like like that anymore" |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| About overstock and Sensus, I have a positive opinion. My sister ordered the 2" king topper and it weighed 36lbs, yielding a density of exactly 5.3lb/ft3. It has the trademark pink color and super smooth texture. It's for real. I may even (either the height of hypocrisy, irony or some dysfunctional combination of both) order one for myself. |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| Jim is right about latex lasting longer than most, heck ALL foam products, there's just one problem; I HATE LATEX! But if you do go the foam route make sure you get something with a density of 2.8lb/ft3 or greater, light weight stuff wears out FAST! Jim, it's also of note that the thinner a layer of foam, that faster it wears out. (I need a physics major to tell me why) For example, a few years ago I put a 1" slice of HD36-HQ foam from foam distributing.com on my bed; it was totally shot inside of six months! BUT the 4" thick layer of the exact same foam within my mattress seems to be holding up very well after 6 years of use, the 12" thick base layer is ageless and seems brand new. But I take great pains to seal my mattress from the air, oxidation is the main cause of poly foam degradation. |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| It ma also be notable that none of the foam on my mattress has discolored. The white HD36-HQ is still snow white, the Sensus is still pristine pink and the Lux-HQ is still baby blue. I'm tellin' ya if you can seal up a foam mattress against the atmosphere, it preserves the foam greatly. (Tempurpedic mattresses come with such an air tight cover, I think) |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| Jim, about sensus not giving support, Of course it CAN'T give support, no memory foam can, only the firm understructure can do that. It's got an IFD of 12, I believe, I just use it to take a bit of the bounce out of all that poly foam. IMO, the less the better 2" is perfect for me 1" might be better for some. I "trialled and errored" an awful lot to find find what works for me. While i suspect that most people would find my bed very comfy, some might be put off by it's firmness. (Remember the sensus is buried under several layers including that monster wool comforter!) lol So anyone looking to imitate me be warned; figuring out exactly what you like isn't so easy! |
Re: I made my own "Hybrid" mattress. Has anyone else done the same? What works for you?
| Has anyone else assembled their own mattress? I'd like to hear your story. |
