Let me start off by saying I have been a long time reader of this site and the other site you were on. I have been able to get all the information I needed by searching and reading the numerous posts. I have now gotten to a point where I need assistance of someone that has way more knowledge than me.
I moved into a new house and bought a king size bed this summer. After all my reading I had decided I was going to get a firm S mattress along with a latex topper for comfort. I found a great deal on a Rejuvenite latex topper. I went with the plush which is clearly labeled by Latex International as 19ILD. While shopping for the perfect coil mattress I visited stores in my area. I even brought my topper into one store and tried it on top of several mattresses.
Somewhere along the way I just decided to bite the bullet and go all latex. As I said above, I had already spent hours reading other peoples reviews and findings good and bad with the various companies. I even spoke to several on the phone and asked them questions as well. Despite your recommendations and others I decided to go with FBM for my core. I know in the past the reviews were hit or miss, but they had seemed to generally be better within the last few months.
I ordered a king sized Firm latex core. By FBM specs it is Talalay 36 ILD. I received my core the first week of September. As soon as I received it, I thought something was strange because it was 1 piece and wasn’t very jiggly or lively like I was expecting. I was concerned at first, but I put my Rujuvenite on top and gave it a try. We slept great at first, but my girlfriend complained it wasn’t soft enough so I bought a 1" latex topper from SLB in 14 ILD. When I got the new topper I tried a couple of configurations and eventually removed the Rejuvenite cover completely. So I had 6" FBM core ??, 3" L.I. 19 ILD, and 1" L.I. 14 ILD. It felt really good to me for about a month, but eventually I started having some lower back pain. My lower back pain is very mild, but stays with me most of the day. Usually by nighttime it has completely gone away, but returns when I wake up each morning. Now it has gotten to the point of staying with me all the time even though it doesn’t limit me in anyway. It is more of an annoyance, but occasionally someone will notice me favoring it or walking funny. Also, I am a combination back and side sleeper. I have been making an effort to be sure I’m not in a twisted position making my problem worse.
My bed is a platform bed with wood slats. After further inspection, I noticed quite a bit of sag in the slats under my side of the bed especially in the two slats under my rear end. I am 6’ and 215 lbs, so that wasn’t really surprising to me. I got out the 2 pieces of 1/4" pegboard I had originally bought when I got my bed for a base. I had tried them over top of the slats for a night or two when I first got the bed but it seemed way too hard to me so I removed them. After added the pegboard a second time, I seemed to get some relief for a few days, but the pain returned. Then I removed the 1" 14 ILD topper from SLB thinking my comfort layer was too soft, but the pain remained even after a couple of days. I even slept on just the core and 1" 14 ILD topper, but this is definitely too firm and doesn’t allow me to sink in enough and I had pressure points almost immediately. My core seems soft and giving in a way. If I sit on the side or just push down with my hand I can push way down near the bottom, but this seems normal from what others have said. It is definitely not hard as a rock or anything.
At first, I was thinking the difference between the my 19 ILD comfort layer and core was too great and I’m feeling that. Since the beginning I’ve thought about buying a 1" 28 ILD layer to see if it will help with the transition. After additional reading, my low back pain sounds like symptoms from my hips sinking in too much from the lack of support. I know the first component to blame will be my core from FBM since nobody knows what it is of course. This week I decided to remove the cover and inspect it. What I found is very interesting. It is has two labels on the side. One is Arpico 100% Natural Latex Foams. www.arpicorubber.com, Richard Pieris Natural Foams Ltd. www.arpicolatexfoam.com. The other label has an arrow pointing up. Order No., Size, and Density and Reference number.
Upon further research it seems the core is probably Dunlop latex instead of the Talalay that FBM claimed? The Density is listed as 75 which would be soft according to the Arpico website. I’m not really sure if this is good or bad, but at least we have some idea of what FBM has sold me.
At this point I’m confused and don’t know which way to go next. Sorry for the long first post, but I have tried to give you all the information that has gotten me to this point. I appreciate any advice and recommendations you can give me to help alleviate my back pain.
Thanks in advance.
