Purchased a 2” Celsion topper and zippered terry cloth cover from sleeplikeabear.com.
It was delivered yesterday and here are my impressions:
We plan on sleeping in this configuration for a while then will decide on next move …I’ll post any revelations “we” observe. Previous posted

. My wife being allergic to almost everthing I worried about putting it on the bed right away but after returning from the YMCA we changed the sheet and put it on under the bottom fitted sheet (tight fit!)

im really not sure how they accomplish this. but I am reminded of a great hands on lesson in the classroom a while back....our teacher just asked us what the coldest object in the room is, almost everyone would say the steel legs on our desks. but every single item in that room was exactly the same temperature (except maybe something sitting in the sun). Natural Latex itself is actually a very poor conductor of heat, this is precisely the reason why they use a pincushion mould to distribute the heat evenly throughout the product in order to cure it. I know that in order for something to literally feel cool to the touch it has to be a good conductor of heat, so I have no clue what on Earth they are adding to this material to give that effect. I also know that this doesn't always translate into something that actually sleeps cooler. Take silk for example. Silk is a good conductor of heat compared to other natural fabrics, which is why sometimes it is referred to as the coolest sleeping natural fibre you can use. This is true in the case of a silk filled duvet or mattress pad (with a cotton cover) as silk fleece can breathe very well. However when the product is woven into a textile fabric it actually doesn't breathe very well at all (silk is used to make parachutes). It might feel cool to the touch initially but it might actually sleep warmer than cotton and definitely warmer than Linen (Flax is a poor conductor of heat by comparison) and truly the coolest fabric to sleep with. In short...the breathability of the foam and its ability to deal with moisture is what will actually effect how you sleep...I don't really see how it can functionally sleep cooler than other varieties of latex foam...unless there is some concept I am maybe not in full understanding of, or something I am missing entirely. |
| I actually tried a Celsion topper, mainly to combat heat issues. In the end I did not find it any cooler. It might be cooler for the first hour or two, and it did seem cooler to the touch. However, evenentually it warms up via body heat to about the same temperature as other latex. At one point I was actually measuring temperatures, and it heated up to about 90 degrees just like my blended latex (after a few hours). So, I am skeptical that it is a breakthrough. Maybe the surface can dissipate the heat slighlty faster, but eventually it warms up just the same (in my opinion). I have the same opinion for Outlast fabrics as well, based on my own use. |

That seems to fall right in line with what should be scientifically accurate. It might feel cooler to the touch initially because it can perhaps conduct heat faster, however after a time the temperature difference is null. When it comes to talking about people sleeping cooler and or warmer its really important to understand that unless something is warmed by your body heat everything in your room at night is the same temperature. The only items that will actually effect the temperature of the air around your body significantly will actually be the duvet and sheets you use, as different fills trap in more air than others. When it comes to mattresses, heat = humidity. You really just need something that can keep you dry. This message was modified Mar 31, 2010 by budgy

| I would note that when I use Sensus memory foam on top, it does seem hotter than when I use latex or a "cooler" (supposedly more breathable) type memory foam. I have used it more than once with same results. I assume that is because it does not breathe as well, it traps more humidity and moisture? Logically, it seems like it would heat up to the same temperature, but I guess moisture retention might be different. |
Not sure how it works but it does sleep cooler . My proof is that I'm not getting stuck with covers being thrown over on me as my lovely wife experiences those female dreaded hot flashes. Checked the LI site and NASA site re phase change material. Both make sense in that the phase change material creates & uses the micro-climate of your body and regulated the long term environment cooling (read that evaporative )abilities by mitigating the necessity to sweat by absorbing heat. Heating is done by the reverse (releasing that absorbed heat). The body doesn't just get hotter and hotter all night it cycles too regulating its' core temp to 98.6 (theoretical ideal) by sweating (cooling) or shivering (heating) Just my 2 cents as the engineer in me analysis everything |

Celsion topper is 2" thick encased in the Terry cloth zippered cover (also purchased from SLAB). It is placed on top of an 8year old Serta Perfect Night, non pillow-top mattress then covered by the fitted sheet. I am comparing the Serta with and without the Celsion topper/cover....Nothing else has been altered except possibly the ambient room temp (which should have been a negative contributer as the nighttime temperature has risen over the last 3 from the mid teens to the low 30's. Before you jump to the furnace possibly being on during the nights when the temp was in the teens, we set back our thermostat to 50 at night because of those "hot flashes". I've joked with friends and neighbors that I was possibly going to have to run an air conditioner and the furnace simultaneously to accomodate the minute to minute Jeckyl and Hyde hot flashes cause |

Okay, so are benchmarks are a bit different. I was comparing it to blended Talatech latex. I am not sure what foam would be built into the top of an 8 year old Serta. If it is PU, then I would agree that the Celsion would probably be cooler. However, if the Serta is pretty firm with little foam on top, then I would have thought that would have been reasonably cool already. The real test would be for you to put try a blended latex or 100% natural latex topper, and see if the Celsion is cooler than that. But, if it is working for you, that is great.

| I'm certainly not saying the OP is incorrect, as I have not tried Celsiun at all. But I would suggest that sleeping on a good fluffy but not-too-thick wool or one of the other toppers Budgy mentioned might have more of an effect than the Celsiun. So if you want even more coolness you might try wool or one of the other things. But hey, if the Celsiun is working well enough for you, all I can say is, Great! |

It's now been 6 nights sleeping on the celsion topper and I still haven't had any covers thrown over on to me so I believe the claim that it sleeps cool. Ambient temps hit the high 80's for three of those 6 days, all three were record high temps (one even broke a 120year record) Nighttime temps dipped into the high 50's which is really hot this time of year in upstate NY. We even broke the overnight high temp on two of those nights. (AC units are still stored in the attic so these nights were sans air conditioning) I'd say for myself and my wife this purchase is a big thumbs up We did previously try an approximately 1.5" thick wool topper (my wife purchased it so I can't give details on make and cost) but this, (the celsion) seems to sleep cooler (for us at least). I didn't like the wools tendency to flatten out under my 260+lbs so I think any air pocket(s) crushed overnight under me. Went back to a cotton mattress pad after about 6 months until we got the latex this year. Cost of the Celsion topper is it's only drawback ($466 for a 2" eastern king) but for me not getting those extra covers thrown on and taken off of me multiple times during the night justifys the cost many times over. |
