PU/Latex/Memory Foam Mattress
|
Has anyone put together a mattress with PU base, latex in the middle, and memory foam on top? I was laying on a Simmons ComforPedic the other day with this configuration. It felt like Temperpedic support laying in it, but it didn’t have that hard feel when you roll over or sit on it – it actually had a little spring to it. When I was looking at it in a showroom, I was able to see some of the specs on the sheet the sales person was holding: Top layer: 4.5” 5.5lb memory foam – ILD unknown, but possibly 2 different foam ILDs (springs back faster than Temperpedic) Middle layer: 2" 24 ILD latex (said it was to dissipate heat) Bottom: 7" 30 ILD foam (I'm assuming it's PU, but I'm not sure???) From what I've been reading about foam lately, I thought a combination like this would be too soft, but it was really supportive. After laying in it for awhile, it did seem a lot cooler and more comfortable than a Temperpedic. The price for the above configuration was $4200. Any ideas on putting one together for a lot cheaper? |

Has anyone tried the Foamex Aerus? I didn't notice anything being mentioned about it having faster recovery on their website, but that would be something I want. It also sounds like it offers more support than traditional visco - I wonder if that means you can go thicker without sinking in too far? This message was modified Nov 1, 2007 by steve2u

Re: PU/Latex/Memory Foam Mattress
| Steve, you're right about Aerus not being advertised as "faster". After researching all these foams, they start to merge together in my mind. I was probably thinking about Isoform. I am very interrrested in this foam, as it is claimed to be "breathable" and "faster remold" than traditional memory foams. Also, it has the best rating on epinions and is more reasonably priced than Aerus. It is also a 5lb foam, compared to Aerus's 4lb. I was really torn between it and foambymail's pink 5.5lb foam. Of course if you read my foambymail thread, you'll see that the foambymail is really a 4lb foam, and may be hot sleeping. I probably should have gone with Isoform. |

| Thanks for the info. I was just about ready to order a 3" Sensus to get my new mattress started, but I think I'll take a little time to read some reviews on the Isoform first. |

Isoform is a memory foam I have been wanting to know more about. Here are my own notes on Bergad Isoform: Isoform memory foam. "100% American made using American technology and labor". Claim to be "more open than other foams." This is "fast" foam. Not "chamber foam." Bergad mattress rated 4.5 stars on epinions with 130 reviews. Topper rated highly also. Strong smell. Reportedly poor customer service and shipping. Density: 5.0 to 5.3. ILD: 15-17. Yellow in color. www.bergad.com is redirected to www.isoform.com As far as I know, Bergad, the manufacturer, is the only retail source for this foam. I have been unsuccessful in acquiring a sample. Edit: I may have a sample of this memory foam, but I don't know for sure. I have a chunk of foam from "Vitalityweb" but I have no idea who makes it. It's the same yellow color as Isoform, but this doesn't necessarily mean it's Bergad foam. Not every manufacturer has a trademark color, so this may just be what color memory foam is by default. Edit: Here is an article about how Bergad purchased their own foam making machine in 2003: http://www.pittsburghlive.com/x/leadertimes/s_117969.html This message was modified Nov 4, 2007 by haysdb

Re: PU/Latex/Memory Foam Mattress
| ILD of 15-17. Maybe that's why several of the epinions posts stated that it was a little too firm. Some of those who commented on the "too firm" issue still rated it 5-stars, though. |

I again requested a sample of Isoform memory foam and this time the response was "I would be happy to send you a sample and some information." Maybe they have someone new working in customer service. Bergad/Isoform is a company that has flown a little bit under the radar and I'm not sure why. They are actually one of a very few "name brands" of memory foam made in the U.S., the others being Foamex/Sensus & Aerus, and Carpenter/Isotonic. Who has heard of Essentia, AdaptaFlex, Viness, Vitality, Vx, or Dual-Peak? This message was modified Nov 6, 2007 by haysdb

Re: PU/Latex/Memory Foam Mattress
| Has anybody used foambymail 2.0 lb/ft3 conventional foam mattresses? I think I'm going with 3" Sensus top over 2" of firm latex or Energia (to give it a little spring) over polyurethane foam, but I'm not sure what firmness to go with for the poly (HD36 or Lux), or if I should do two different firmness layers. Any opinions? |

Steve, I have had no experience wiht foambymail's PU foam, but judging by the way they over-sold their memory foam density, I wonder if it really is 2.0 - it may be 1.5 - who knows. Any way, 1.9 or 2.0 PU is considered a 4-5 year foam - you may want to consider a 2.5 to 3.0 HR (high resiliency) foam. These are more like 10-year foams. Here are a some sources: PerfectFit is an upholstery supplier, and the foam sizes listed are not quite large enough for a king-size bed, but they say that other sizes are available. Looks like reasonable prices. Foam On-line does custom sizing, but seems expensive. Simple-pedic has a price calculator and seems very expensive. This message was modified Nov 7, 2007 by donw

FoamByMail's "HQ" foams, HD36-HQ and LUX-HQ, are 2.8 lb foams. The LUX HQ is an ILD 55 and will be VERY firm. I might use 2" of that for a bottom layer but I think an entire core of that would be too firm for the vast majority of people. You have to custom order a size to get it. Their standard mattresses are the 2.0 lb foam. Energia is nice, if somewhat pricey. It's a very definite step up from a conventional PU foam. It doesn't quite achieve a latex feel, but there is no question it's a high quality foam. I received a sample of memory foam from IsoForm. Some of the information I had about this foam was wrong. For starters it's a light green in color, not yellow. I would not call this a fast foam. In fact out of all my samples, I'd call it the slowest of the lot. It does have an open cell structure. I would call it a "coarse" cell structure but not with any negative connotation. This is the first foam I've received that literally freezes into a solid block. All of the Foamex foams, including Sensus and Venus as well as the foams they make for Sleep-Aid and FoamByMail, get firm but do not actually freeze solid. It gets softer and responds more slowly when it's warm, vs. room temperature. I would definitely call this a temperature sensitive foam. I wish I had a sample of Tempur foam. My guess is that Isoform is very similar to Tempur foam. It's a dense (5.0+) foam that's temperature sensitive, and like Tempur foam, it's a relatively firm foam, as memory foams go. For someone wanting a very traditional memory foam feel, this fits the bill. I would "rate" FoamByMail and Isoform about the same. This is VERY subjective. The FBM foam recovers just a bit quicker, is less temperature sensitive, and has a finer and more consistent cell structure, but I suspect the Isoform might sleep a bit cooler because of the larger cell structure and higher permeability. That's just my educated guess. Both seem like a good value at around 2/3 the price of Sensus. This message was modified Nov 8, 2007 by haysdb
