Mattress Surgery Help?

I've was looking for a new mattress and in my search came across this site. I was just looking for something to give me a better night’s sleep, something to help me feel more rested in the morning. I tend to toss and turn a lot.  I saw the posts about mattress surgery and figured if I was going to throw out my mattress why not try some surgery first. My mattress is a 2002 Simmons mattress. I figured I'd just remove everything and was left with just the coils which are in very good condition.  As everyone else who has done surgery has noticed there is nothing but cheap foam in the mattress. This was a non flip mattress. On the bottom was 3/4 of an inch of light PU foam. The top had a thin fabric on top of the coils, then the same 3/4 inch light weight foam. On top of that was a 1 additional inch of the same foam. The top layer is comprised of a thin soft egg crate piece, a very soft 1/2 inch foam piece and some fabric all sewn together. I'm trying to figure out what layers to put on top of it. Right now I have the cheap 3/4 inch foam that came with the bed, and a 1 inch latex (32 ILD from FBM). Feels pretty good but can feel the springs a little bit. What good HR foam should I put between the 1" latex and the springs so I don't feel them? I don't want to put too much HR foam and take away from the feel of the springs; I just don't want to feel the springs. I am very happy with the feel of the latex from FBM so I intend to order the HR foam from them. Should I get LUX HQ ,HD36 HQ, LUX Reg - and how thick? Really just looking for the thinnest amount so as to not change the feel of the springs but to not feel the springs, if that makes sense. The 3/4" cheap compresses so much it’s like it’s not there. . Eventually I’m also planning on getting an additional 1" of latex 20ILD on top of the 1" latex 32ILD I have now. I like the feel of latex. The 1" pieces of latex compress a lot and feels soft so I doubt 2" total will be enough to not feel the springs. Definitely think I need this piece of HR foam after the springs. Any recomendations would be appreciated.

personally i think because the Simmons coils are conforming and forgiving that just a 2" layer of soft, medium or firm latex depending on your comfort preference could do the trick.  I wouldn't worry about the 1/2" layer underneath the coils its a solid bloc foam that is meant to basically never compress and give a good seating edge for the coils.

Thanks for the reply Budgy. I intend on adding an additional 1" of latext to the 1" I have already bought. The problem is i don't have any good foam between the latex and the springs. I'm wondering if I should get a piece of HR foam. I don't think 2 " of latex will be enough to not feel the wire. If i fold the latex I have now in half , so its twice as thick, and lay on it I can still feel the springs. Are you saying not to worry about getting a piece of HR Foam (1/2 inch or so) or did you think I had it already ?  I know people here really don't like HR foam that much but this piece would be just so I don't feel the outlines of each spring.  Or would it be better to get an additional 2" of latex for a total of 3 inches of latex.  Would that be enough not to feel the springs? A one inch piece of latex is around 80 dollars while a 1/2" piece of HR foam is 15 dollars.

quick question for you....is this a Simmons Beautyrest?  Because I have literally laid on the springs with no upholstery and they were fairly comfortable. in which case I dont think you will need to have much more than 2 inches of latex if at all

Not sure. Can't find that info on the tag. The only #  on the tag are PA-25425 /  M96001.70.6002  / HillsB  . Can't find anything about Beautyrest. The springs are fairly comfortable. The only problem is that the 2" of latex compress enough that you can feel the outline of the individual coils and the wiring holding them together. I don't have any experience with HR foam but I’m thinking a 1/2" piece of HR Foam will not compress very much and because it is so thin it will not alter the movement of the springs. I can try the HR Foam, go with another inch of Latex, or any other option you can recommend.

Take a picture of the springs, that should answer Budgy's question.

ahh okay, you did actually answer my question...if their is helical wiring holding the coils together and not fabric encased it is not a beautyrest, it is a bonnell or continuous spring.  I would recommend doing a really thin layer of something directly over the springs something with a very high abrasion resistance...like coconut coir or rubberized coconut coir.  I am not sure if you can buy sheets of it in small quantities but it would be the perfect material to place right over the steel...a thin 1/4" sheet would be more than enough to buffer the feeling of the springs and prevent the latex from getting mashed directly into the coils themselves.

Thank you for your help. I'm going to get a piece of 1/2 inch LUX HQ as that is the thinest HR foam that FBM sells. I still have the very thin sheet of abbrasive resistant fabric that was orignal  over the springs to protect the piece of foam I am going . Any other recomendations besides "coconut coir or rubberized coconut coir" to place on the bottom side of the springs. I'm would like to put my allergy encasement back on but definitly don't want to rip it. In retrospect I should of only removed the top of the mattress but too late to think about that.

coir is best.  but its probably hard to find it rubberized which you would really want or its gonna shed all over the place. 

a thin layer of any fibre like cotton and a really tough fabric like berlap to put over it perhaps would also suffice

Sealy uses a 1/4" or so of memory foam over the springs on some beds.

I am currently using a 1/2" of memory foam on top of my Bonnell coils to soften them a bit and to not ruin the latex on top of them.

Even with Bonnell coils, 2" can be enough for some people. Depends on your weight and so on. I'm using the 1/2" of memory foam, then 3/4" of latex and then .9" of latex and then a 2" wool topper that compresses down to about 1/2". So that's all in all, a padding of less than 2 and 1/4" of foam and then the wool on top of that, and the 1/2" of memory foam probably can count as about 1/4" as it compresses down into the springs...


I am guessing they are not heavy gauge springs if it's a simmons - probably 13 gauge at best, or even 14 gauge. Am I right, Budgy? If that's the case, the springs may not need that much more than 2" of padding. Then again, it's all a personal preference.

Thanks for the reply Jim. I'd put a picture up of the coil system but I don't think the forum will host a picture, I would have to put in up on another site and then link it. After reading a little bit about coils I'm pretty sure this is a cheaper bonnell system. The coils are individual pieces of wire laid out in rows. It’s not one piece per row so it is not a continuous and there is no fabric so it is not a pocket coil. The wires do not look that thick but I cannot with certainty tell the gauge. The mattress was only 400 or so dollars when I got it, I doubt it’s anything good, was also 8 years ago. I'm looking for a better night’s sleep so why not try the surgery. It is kind of fun opening it up and seeing how companies use cheap stuff and then sell it for a lots of money. Plus buying layers in 1" increments you can find what works the best for you. Since I am really just playing around with this I'm trying not to spend that much money. This is the reason I'm using FBM is they are very competitively priced. So for my budget mattress surgery I'm going to end up with the coil system (already had), 1" 32IDL latex ($80 FBM) , 1"20 IDL latex ($75 FBM) , cuddlebed ($35 Costco). The cuddlebed is not foam correct? Its just polyester fibers like my pillows from what i understand.  The only missing piece is the layer between the latex and the springs. 2 inches of latex and then the springs will not work for me. It’s not that it is uncomfortable, it’s just that the latex compresses enough that I can feel the outline of the springs. So that is where the 1/2" layer of HR foam would come in. I know you said some companies put memory foam as this layer. In my mind memory foam would compress more than the HR Foam and not do that job as well. It would also cost a lot more. The main job of this layer would be to prevent the layers of latex from sinking through the spaces in the wires while minimally affecting the firmness/softness of the actual set up.. For a second I was thinking just to put some corrugated cardboard as the layer above the springs. Do you think the HR foam is a bad idea? I know you are not a fan.
