What should I do with old, bowed support slats?

Hi bobkbed.

Thanks for the informative post about your slat foundation without center support, etc. You must be really quite handy and creative to rebuild/improve this unit.

As you already suspect, I think with the right 9" of latex, and your center support, you are not going to feel the effects of the bowed slats anywhere close to your old IKEA mattress which was probably 5.6 inches originally (Ikea used to purchase boatloads of 14cm cores from Latexco and Sapsa in Europe.)

As fas as the placement of the "more bowed slats", my instinct says it won't make much difference in terms of sleeper support. The standard wooden 1 x 3" slats with gaps and 2. 5" apart (no more than 3") are about 50% of the total support surface area. While it probably wouldn't be an issue in the shorter term ... the lower surface area in contact with the mattress would result in a greater risk that the latex would sag into the gaps in between the slats over the longer term although it's not really possible to quantify the higher risk except to say it would be "less supportive" for the latex.

While it may be an "abundance of caution" ... if you would like to reduce the risk then an inch or two of very firm polyfoam in between the mattress and the platform bed or adding a 1" rubberized coir bed rug like this  or even something like the  vinyl lattice here  would reduce the risk.

I look forward to any new updates and let us know if you have any other questions.

Thanks for the reply, Phoenix.

I like problem-solving and DIY projects (up to a point...). Cost savings was also a consideration - I don't really need or want a new frame just yet.

I had the lumber store do the cutting (I have no power saws); I just did the sanding. I already had a upholsterer's staple remover. All I needed was to buy a staple gun.

Removing the old staples was easier than I expected, and I was able to re-use the cloth webbing. Getting the new slats aligned and the webbing in place was tedious, but straightforward. (Wish I had a basement or a workshop...)

Thanks for the suggestions for additional support. Now that I'm comfortable working with the staple gun and slats, I realize there's another option: for the same or less than the coir mat, I could replace some of the slats with wider ones, especially in the middle. For now, though, I think it's good enough.

I have a question regarding out slats (or possibly replacing them altogether).

I've just bought a used lovely cherry four-poster bed and a DreamFoam Aspen 10" Latex mattress to go with it. I'm having some trouble with the slats to support the mattress.

The bed is a queen - 60 x 80 inches with 1 inch wide wooden supports down each side (see photos). The bed came with 4 slats which are a little out of shape.

The bed does not have a center support beam so I'm worried about using slats or even a drop-in foundation. I've been looking for a reasonably cheap way to support the mattress.

My first idea was using a drop-in metal frame with wooden slats (like this ) that would rest on the side supports. I worry that this will bow in the middle over time or just plain snap under sufficiently active bed antics.

I've also looked at installing some kind of center supports (such as this or this ). With these it seems I might be able to reuse some of the old slats (with a few new ones added) or drop in a wooden foundation such as this .

Alternatively, are there are metal wire bed frames with legs that will fit inside the bed frame? (so that it is not resting on the side rails at all). I was thinking of something like this .

It seems like this is a common problem but I haven't come across a definite solution yet (or at least, not one that won't cost $400+).

Any advice would be greatly appreciated!

Hey aashmore,

If you're up for a little handyman project and have a lumberyard nearby, consider this, which I just did a couple of weeks ago with my queen bed frame (see photos).

The center support is a 1 x 4 and the legs are 2 x 3s. Sleepworks, a reputable local store, said pine would be fine, but I chose Douglas fir, which is stronger.

To determine the leg height, measure from the floor to the top of the side rails on which the slats sit, and subtract the thickness of the center support board (3/4" for a 1 x 4).

If your floor is uneven, consider adding threaded furniture glides screwed into T-nuts on the bottom of the legs (cutting the legs shorter accordingly). I didn't do this, but saw it in these center supports sold in the UK:

www.bedslats.co.uk/universal-bed-centre-...-feet-for-flat-slats

For additional slats (which I described in a few posts back), I used oak, since the original slats were oak. If I could go back, I'd use fir or poplar, which are much cheaper and sufficiently strong, and I would have used 1 x 4s instead of cutting them to the same 2 1/8" as the original ones.

Since I don't have a table saw, I paid the lumberyard to do the cutting. I've heard that places like Home Depot don't do accurate cuts, but I haven't tried them myself.

I attached each leg with a single 2 1/2" star-head deck screw*. Sleepworks recommended screwing the center support to two or three of the slats, but I haven't done that yet and might not ever do it unless the center support moves.

My new mattress (a 10" latex mattress from Foam Sweet Foam) has been on it for four nights so far, and all is well.

Hope this helps.

Bob

* Originally I used cheap wood screws, but a friend turned me on to good-quality star-head deck screws. Even though I'd drilled pilot holes, the heads of the cheap screws stripped. The star head screws were fantastic - no slipping or stripping.

Hello!
First time posting after lurking quite a bit around these forums when I was investigating purchasing a mattress topper (ended up with a N1 Talalay 3" topper). When it's time to move to a king size bed this will be the first place I go to for information and purchasing.

Anyways, the reason I came to this particular thread is that I wanted to get an opinion on certain kinds of heavy duty metal platform frames that have been appearing recently. I recently purchased this one (Zinus Elite 14"), though I'm considering getting this slightly taller one (16" knock off by Ziyoo) for better under bed storage when it's released in queen size. My main concern after reading through this thread is that it's hard to tell if such a frame offers sufficient support for a mattress.

Right now I'm just using barebones spring mattress with a topper that I plan on replacing eventually so I'm not concerned about it, but I would like to use the frame again on something like a full latex mattress in the future. is a picture of what it looks under the bed currently with a bed skirt. To me it looks like, because of the large amount of horizontal bars, it ends up giving pretty good support. Definitely better than my old box spring if my last couples of nights of sleep have anything to suggest.

The spacing between each of the vertical bars is 6 inches and each of the horizontal bars is 9 inches except the center and outer bars which are significantly closer (less than 3"). The bars are pretty much all 5/8" with some of the outer ones being closer to 1/2".

Looking forward to hearing your thoughts!

Are you placing your latex mattress directly on top of this frame of are you using a box spring and then the mattress on top of that?
If you will be using a thick latex mattress (let's say 6" or more), my suggestion would be to purchase a a flat sheet of plywood or something the likes (drill a few holes in it for ventilation), place that on top of your metal frame, and then put your latex mattress on top. The reason is for that suggestion is that because latex is not stiff, it will squeeze through the openings (particularly where you body weight is applied) and then your sleep will not be as good as it could be.
