Can these be used under the mattress and box springs without the frame? Would 2 sets give more support/center, etc.?

No. You definitely need a bed frame to properly support the mattress and box spring.

It's shipped with three wood slats that screw in place and each slat has a support leg in the center. Just the three slats probably isn't enough support for a mattress without a box spring, but the lip that the supplied slats rest on runs the entire length on both sides of the frame, so you could easily throw some more slats in there (or a sheet of plywood) for more support.

they would if you bought enough of them. i don't think you could make them hold up the mattress in the middle. you would need box springs under your mattress in order for them to work. you would have to but a couple on each corner of the bed and two or three sets in the middle.

No. you could get some plywood and put that on top of the support system, but the spacing of the support system alone is too wide to support your mattress without a box spring or plywood under the mattress.

The frame collapses and is two independent pieces that are placed next to eachother so it would definitely depend on what you used as a riser. there are 8 points of contact with the ground so to be safe, you'd likely need solid platforms or risers to make it work. Also, the frame itself is oversized so the risers would probably extend out below the mattress

The bed frame don't have the support to hold a box spring so the box spring will move a around on you when you lay it on the frame. So my opinion would be just to uses it with just a mattress. But I love the bed frame.

Definitely does not need a box spring. In fact you should not use a box spring. The bed is very thick. Place it on a frame and it will end up higher than the old frame/box spring/mattress combo. And I like the higher profile.

I don't see how even 8 of these would work. You are trying to get the box spring or mattress to do the work of a frame. But frames are rigid and have cross bars to keep the mattress from sagging in the middle. Even with a frame you would probably need more than 4 of the lifters.

If I am understanding correctly I think it would be too risky. Most box springs are wood frames covered in fabric. If you are thinking of boosting up on these instead of a bed frame, every time you move your bed it would slip off to the side. You really need the leg of the beg to insert into the hole.

I think so. I have a set of bed frame to go with it. It will be a little low without a box springs or a frame. Hope it's helpful :)

You probably could put casters on. I would not as the frame and bed probably combined are easily moved without them. There is plenty of space underneath already to vacuum under when needed.The whole bed frame plus mattress weighs hardly anything compared to regular beds. That makes fairly easy to move even without casters on.

The support is in the middle but it hasn't stopped us from storing things under the beds. The platform for the mattress is high enough that we can get good size boxes underneath. The center supports are nothing more than a 1" square post. We actually put some of that foam water pipe insulation around them to save our toes.

You do not need box springs, but can use them if you like your bed a good distance from the floor.

No, not unless you put a piece of plywood on it first. Also, without a box spring your mattress would be really close to the floor.

No, due to the height of the rails. The rails are not tall enough for both a mattress and box spring, the mattress would slide right off due to not being contained by the rails. But the bed frame is made to not need a box spring at all, which is how I use it with no problems.

I do not believe this frame will offer the same support as the slats you have without a box spring.

I would not recommend a box spring for this platform bed set. I have been using this set with a mattress only (Signature Sleep Contour 8-Inch Mattress, Queen ) and it works beautifully!
