Spent one week on a Sealy posterpedic cushion firm innerspring at my parents house. It was not very thick and stuffed with a lot of foam. Pretty bare bones by todays standards (they got it about 7 years ago). They did not know how much they paid for it, but I assume one of the cheaper ones (I don't think they would spend a lot for the spare room). Definitely felt firm and had pressure points. However, I seemed to sleep pretty well. Slept more hours than usual (possibly due to vacation aspect?). Did not seem to get too hot or too cold. Not sure if the difference in blankets had anything to do with it. I have read that a firmer mattress will be cooler because you sink in less and have less contact with the surface. There may be something to that. No aches or pains in the morning, but perhaps felt a little more beat up from the firm surface. Comfort wise, I would have a preferred an inch or 2 of nice foam on top. Overall the latex bed definitely feels more comfortable. The moral of the story is that I probably can take a firmer mattress than I thought. I also had a Sealy Posterpedic for 22 years prior to my recent attempts at finding a new mattress (with 2" of added memory foam the last 5 years). Also, it seems to confirm that latex holds heat more than an innerspring. So, I am now wondering if I am better off with a relative cheap innerspring with possible addition of some latex and or memory foam? Not sure if adding 2" will bring the temperature right up to the level of a pure latex mattress. I have a cheap innerspring in one of my spare rooms (full size though), so I may add something to that to check the temperature level. I don't remember having as many temperature issues on my old Sealy plus the 2" of memory foam. One of the cheaper queen Sealy's (not much foam) on US mattress goes for $550 with 732 coils and 14 gage. Not sure if that is good enough springs. Meanwhile, I am getting 1" of Celsion latex tomorrow. Will see if that has any impact on temperature issues for me. |
| I haven't actually noticed sleeping much warmer on my xfirm latex mattress, but I have also read that they sleep cooler than memory foam mattresses, due to the sinking in with memory foam, as Kait says. |

I used one inch of added Celsion last night. At first I tried it on top of the mattress cover to see if it would work any magic. It did not. Still seemed too warm. I heated up to 89.6 degrees below the Celsion (and above the mattress cover). Frustrated I decided to put in under the mattress cover. It heated up to 90 degrees just like the Talatech. Can't say I noticed any difference. Will have to try a couple more nights to be sure. I switched to XF over XF over F to make the mattress firmer. I have had the sensation of sinking in too much and that helped. Getting pretty frustrated at this point. I think the basic thermodynamic properties of latex and memory foam mean that they will retain heat and reflect it back. I guess it is warm an cozy to most people but I find it a bit too warm. It does seem to affect my sleep. The only thing I have found to sleep cooler is a firm innerspring. The tradeoff there is less comfort. Making it more comfortable with added latex or MF will probably bring me right back to the heat issue. Maybe cotton or poly padding would be a cooler option. At least I would have the option of going cooler if necessary. Cheaper and perhaps better support as well. |

I follow your logic and agree. I personally really like my poly-fill mattress topper. It is very comfy. My mattress was made with some PU foam over the cotton over the springs that I like...and after a YEAR the one side FINALLY broke in, and butt-dent time again. Not uncomfortable, just aware of it. So we flipped the mattress. I had tried that once before but the foam was too firm for me so flipped it back over to orginal side. Anyway, we flipped it and put the fluffy polyfiber topper on it and it is just lovely. I think these work well for too firm mattresses. Not sure about the insulating qualities, tho. I sleep cool and always like covers. Kait |
