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? |

The edges of the bed were much more firm. I think that the Sensus topper may be too sensitive to heat for me - it just doesn't seem like it could offer adequate support when it's that soft.
32 ILD latex will be MUCH firmer than the Sensus. A whole different feel, not even in the same ballpark. I don't know if that will be good or bad for you. 32 ILD latex is generally not considered a pure comfort layer. |

I had a 2" ILD 32 latex topper from FBM. I was using it under something else, not as a topmost comfort layer, and I still found it to be too firm for side sleeping. I was "afraid" to go all the way to 2" of ILD 20 so I compromised on 1" of 20 and 1" of 32. Still too firm so now I have 2" of the softest latex I can find on order. Moral: this forum is very much of the firmer is better persuasion, and for the support layer I agree (up to a point anyway), but for me this does not extend to the comfort layers. I would have been perfectly happy with any of my configurations if I slept on my back, but for side sleeping it was very easy to go too firm. |
Re: PU/Latex/Memory Foam Mattress
| Steve, I would recommend 2" of Isoform. It isn't supposed to be as soft as Sensus, and is supposed to be cooler. But you may be one who cannot sleep on memo foam at all. You could try a 1.5" to 2" eggcrate PU topper on your current base foam. They are pretty cheap and could be discarded every other year. Two inches of 20ILD latex may work for you, but I have to agree that 32 seems too hard on top of your pretty firm PU. How firm does that 50ILD LUX feel, any way? |

The 36 ILD is still pretty firm, but allows you to sink in a little. I never did receive my Isoform sample. Maybe 2" of 32 ILD latex under 2" of soft poly or 2" of 20 ILD latex would be better for me? |

Here's my latest idea: 1" soft poly 2" of 20 ILD latex 2" of 32 ILD latex or 1" soft poly 1" of 20 ILD latex 3" of 32 ILD latex <over > 3" 36 ILD poly 4" 50 ILD poly With this configuration, do you think this would be supportive with a soft feel (I'm 175 lbs.)? I want to make sure I don't have a hammock effect - sounds like it's common with too soft of latex used in the lower layers. Do most of you with latex prefer to sleep directly on a soft latex without the poly foam? |

The problem with the foambymail 20 ILD latex is that it is really too firm. I had to take out my 32 ILD Latex International (tested at 32 ILD) topper and put that on top. This is softer than the 20 ILD from foambymail.com 1 or 2 inches of 14 ILD LI talalay would be very nice on top. The trouble is, where do you find that, and at what price? When Mark (batman) used to own memoryfoam.com he used to sell it for a fair price, although only in 3" thickness which seemed too thick to me. However the feel was heavenly..... Otherwise memory foam is nice as a top layer. Get the 1.5" thick memory foam from Walmart. That stuff is very nice on top. However it won't last forever. Good luck.

Re: PU/Latex/Memory Foam Mattress
| Jim, I wish you'd seen and responded to my post "is 20ild latex soft enough for top layer" I went and bought a 1" top from FBM, hoping it would work for the very top layer, but it sounds like (at least the one you got) was more firm than your LI 32. I'm hoping for less than 20. I'll let you know when mine comes in. |

Re: PU/Latex/Memory Foam Mattress
| I think my back is getting tired of foam, period. ANY kind of foam. That includes latex and memory foam. I almost wish I had gone with something made of cotton filling like the McRoskey or maybe one of the higher end Kluft ot Aireloom matresses. Oh, don't get me wrong. All my mattresses in the last several years have had foam in them. But, it just seems not so MUCH! Also, as I get older, I just think my back and hips crave a different type of experience in a mattress. But, WHAT???!!! On the one hand, I loved the billowy feeling that my down alternative fiber bed gave me when it was on top of latex and memory foam. But, on the other hand, after awhile it tends to sink in and that can wreak havoc on my lower back. So, I am at a standstill as to what kind of mattress my body will adapt to for the duration. This right lower back pain is NOT going away! |

After last night, the memory foam is definitely going back. My girlfriend is starting to get lower back pain in the morning now. She's a nursing student, so she's at her house on nights she has classes during the week and she's even starting to like her worn out innerspring mattress at home more than the thick memory foam. I have a firm, but springy King Coil in my guest bedroom that we would probably use if it wasn't so small. We are starting to think that a normal medium to firm innerspring mattress is the most comfortable to wake up in. That's why I questioned the 32 ILD latex for, I guess you could say, a pre-comfort layer and not the actual comfort layer. More like a layer to give some supportive spring to the bed that the polyurethane doesn't provide, but I don't want to feel like the middle of the mattress is sagging. My thought was that I can always order more foam and get softer as I go up, as long as I don't go over 13" to 14" mattress thickness. I would assume the 32 ILD latex would be a little softer (and have more spring) than my 36 ILD poly foam. After reading Batman's reply on "Is 20ILD latex soft enough for top layer?", it sounds like 20 ILD latex would be too soft to offer the support that I'm looking for in this layer. To add a little more confusion, I was reading some of the old posts here and some thought the 20 ILD was was useless, then I've read other posts on all latex mattress and most people did not go below 28 ILD for their top 2.8" layer, or it was too soft. I'm going to assume most of these people are talking about LI latex? Can someone compare the FBM latex in 20 and 32 ILD to equivalent LI ILD? This message was modified Nov 30, 2007 by steve2u
