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? |

That whole configuration seems really soft to me. If you're thinking of buying this bed I would recommend lying on it for at least an hour. That may seem extreme but with foam beds-- particularly soft ones-- what feels wonderful initially quickly loses that feeling when muscle fatigue sets in after a few hours of struggling to find support. And while you can always make a firm bed softer there's nothing you can do to firm up a too-soft bed. On the other hand, if you like a soft bed and are interested in duplicating this one for less money, check out foamorder.com . This is one source for both memory foam, PU or HR foam and latex. They also sell covers to hold it all together. There are others out there. If Hays checks in, he can probably give you a list of all of them. I don't know what size mattress you are looking for. If it's king you might think about getting a split configuration, as all this foam can be very heavy very limp and very unwieldy to manage. Also unless you are a big guy, 4.5" of memory foam seems like an awful lot to sink into. Memory foam sleeps hot and the more there is to sink into the warmer you are going to feel. I'd keep it at 2 to 3" of memory foam. Especially over 24 ILD latex which is also pretty soft. |

I think Simmons designed this one to feel good in the store, and not at home. My guess is that you get that mattress home, and you will wake up after 8 hours of sleep feeling very sore due to lack of support. In addition, $4,200 sounds like way too much for a foam bed. Try foambymail.com for much lower prices. I agree with cloud9 about split configuration. At most, get the top layer non-split, but even that is probably not necessary. Good luck, and let us know what you do. |
Re: PU/Latex/Memory Foam Mattress
| Thanks for your input. The ComforPedic mattress definitely wasn't too soft or too hot when comparing it to the Tempurdic - it was pretty firm. It doesn't make sense to me since ILD is ILD - there shouldn't be a variance like one companies medium to another companies firm. The sales person did claim that ComforPedics memory foam layer breathes better than Temperpdic...and it did seem like it after laying on both for about 30 minutes on each. That being said, I still think I would be better off taking the advise of the people on this forum who have slept on foam. I need to do something pretty quick to alleviate this lower back pain - I'm now sleeping along the foot of my king sized Sealy Fenway from Costco since my normal spot has sunk in, but not the 1.5" needed for the warranty. |

Based on what I have been told by some people who should know, and some large samples of various kinds of foam that I have, polyerethane foam feels firmer for a given ILD than does latex. I cannot explain this because the ILD's are measured in exactly the same way. I personally don't think there is anything wrong with a support base of Urethane foam. There is a bias against PU foam here, and for some good reasons, but it can be used effectively. One of the problems is, there is el-cheapo PU foam, with a 1.6-1.8 lb density, there is a better quality 2.2-2.4 lb foam, and then there are some high quality ~3.0 lb foams. If you don't know which it is, that's a problem, because the lighter foam would tend to break down sooner than the more dense foam. That's a whole lotta money for a mattress. |

Here's a link with a little discription of the ComforPedic from my local retailer: http://www.mattressgiant.com/default.aspx?n=69&shop=store&perpage=18&category=MFLX&model=990626 |

I have to agree about the HR polyurethane base. You're correct in stating that the density is important. And, when you look at high density upholstery foam, for instance, think of how well it holds up over time. We've had our couch and loveseat for 13+ years and there's nary a dent or sag in the foam. Of course, we wouldn't want to sleep on something so firm. But, i also wouldn't care to sleep on the low density, cheaper stuff, either. And, believe me, I have! :) haysdb wrote: I personally don't think there is anything wrong with a support base of Urethane foam.
