i have a sleepez bed that I keep trying to soften by adding more layers of foam in the case. So I now have 4.5 layers in a case meant for 3 layers. The case still zips, but I wonder if I am compressing the foam so much that it is affecting the feel. I have talalay latex, which always felt springy to me, but I am wondering if this made it more springy? Or if this is bad for the foam? |
OK ... thanks. "I am sure I started out with 1" then 2", then 3", etc. etc. toppers. When I had less I believe I had back pain." This is also really helpful information as it "points to" a thinner layer being fine for your hips, but we need to make sure it is supportive (has enough resilience) to fill in the small of your back.

OK, I'll try it. The big problem is what to do with the discarded layers and toppers. Right now they are on the floor in our room; thats the part wifey hates the most... By the way, just read the link on poly foams. Interesting, altho difficult to fully understand. On the chart, I assume lower is better? I've always liked the feel of poly foam (ie my couch) more than latex (ie my bed) but worried that poly foams just weren't durable enough for bedding (esp given my weight). Maybe thats not true, and a poly layer would help? |

Using a high quality polyfoam is always an option as a good quality HR foam is slightly less than latex with similar qualities (although in spite of what they say it's certainly not proven that they would last as long). They also I don't believe have the same point elasticity as latex so have some drawbacks there. The chart was very interesting and I spent some time there to make sure I had a logical explanation for the different effects. One of the most interesting things is that ILD is only about the upper 25% of a layer. If you compress a HR foam that is softer in the upper 25% to 65% then it could be much firmer than a lower quality foam which starts off (first 25%) much firmer but doesn't have as much difference when it is compressed and so is softer with deeper compression. This is why compression modulus (sag factor, comfort factor etc) is so important as it is rare that someone actually sinks into a layer exactly 25%. In other words ... the response curve of higher quality HR foam can start off softer but "curve upwards" faster and end up firmer in deeper parts of the layer. If latex was a polyfoam, it would be considered an HR foam. Different formulations of latex will also affect it's qualities although they would all be considered HR.

Leo, (I need to start including who I'm replying to in this thread) :) I'm going to spend a bit of time looking at all the things you tried before I give you any beginning ideas. If you're game for this I am. Should we start a new thread to save confusion in this one or just leave it here? Phoenix |

OK ... lets start a new thread (leave you to start it since it's your project :)) I think it would also help others who may be in a similar boat and who wanted to follow the "logic" of each construction towards (hopefully) a resolution. If I'm getting confused remembering which construction I'm commenting on ... I can imagine that others might be as well (laughing). And yes ... any videos or pictures that may help would certainly be welcome. Phoenix This message was modified Dec 4, 2010 by Phoenix

Not to worry, I am usually confused. Leo I've been reading thru your thread and yes it sounds like we are in the same boat. But separate threads still make sense. Best of luck to you... |
By the way Phoenix I am still here. We had guests this weekend (including tonite) and I normally throw the extra foam in the guest room so my wife asked me not to start experimenting until they leave (tomorrow). In the meantime I've been trying to read thru a bunch of your other posts and thinking back to my research. Truth is I've never spent more than 1/2 on a foam bed and liked it. They feel great in the store for that long, but that doesn't mean much (as I've since found). Is it possible that I would be better off with foam over inner springs? ie are they that different that I could be reasonably comfortable on springs but not on foam core? If you can remember any posts where you discuss this lemme know... Steve |
It's been a busy day so I haven't had the chance to post in this thread with any comments yet. Yes it certainly is possible however it is likely more a matter of preferred feel than the innersprings themselves as the same "issues" and "tradeoffs" of support and comfort apply with them as well. They are just a different approach. More later ... but well before your guests leave :) Phoenix This message was modified Dec 7, 2010 by Phoenix
