Once you install these rails, do you need a box spring or can you place the mattress directly on top of the cross beams?

That all depends on the kids of support you are needing. I would either use additional cross beams or a box spring.

You will definitely need a box spring. The head and foot boards are pretty tall, designed with a mattress/box spring combo in mind. I also copied from Overstock why a box spring is a good idea: Box springs provide both height and rigidity to your mattress. With larger mattresses, where partners typically sleep in the same position, a box spring is essential to keep a mattress level year after year. The height gained by using a box spring mattress makes it much easier to get in and out of bed, and box springs themselves are designed so that the mattresses won't wear out after just a few years of use. Box springs absorb the impact transmitted through mattresses from rough handling and use. You will definitely need a box spring.

The mattress would be able to be placed on the cross beams if you wish not to use a box spring.

With a foam mattress, I had to add additional cross beams to provide adequate support. Box springs or additional cross beams will be necessary to support a mattress.

It's up to you. You can do either, I have mattress directly on top of the cross rails.

No box spring needed...we just put our son's memory foam mattress on the wooden slats. I would like to add that the bed frame sits about 12 inches off the floor so a box spring and mattress would make the bed very high.

I placed the box spring and mattress on the floor. The rails were between the box spring and mattress. Works just fine. Imagine doing the same without the box spring might work and may depend on your flooring and whether the mattress would slip, or not. These rails are awesome.

I did not simply because with the box spring on top of the platform frame slats the bed was about 4 1/2 feet off the ground. so we just put it directly onto the slats...if you purchase just be careful during construction as some of the wood is kind of thin and soft so screws can shred or tear if you have to screw in/unscrew and screw again

Yes, I use a frame under the box spring. Whether it's necessary or not, I couldn't tell you. I just have a regular metal frame, nothing fancy.

No, I do not have a box spring. My bed has storage drawers underneath it and we just placed ply wood on top of the slats and the mattress directly on the plywood.

I used a platform bed frame that has multiple slats and no need for a box spring. It is firm and very comfortable, perfect for that platform bed.

Patricia, this frame is designed for a box spring. I think you would be very uncomfortable placing just a mattress in it and it probably would fall off the narrow metal side frames. There is only one cross beam to support the middle. It would not work well.

I do use a box spring but one is probably not required as long as you have something flat to sit the mattress on.

You will need box springs. This is so much more beautiful than the pictures show. Well worth the money.

The instructions say that a box spring is not necessary. I had both, and it does put the mattress higher than the foot board & you can only see about a foot of the head board, which I don't mind. But the metal slats are pretty close together & can easily hold just the mattress.

You will need a platform or box spring. I put mine in a camper and it is very comfortable.

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.

The rails are held up by spring loaded pegs. Pull back on the pegs and you can lower the rails or pull the rails out of the cross bars that go under the mattress. Generally you would just lower the rails so they rested on the floor. Depending on the bed height this would make the top rail about even with the mattress.

You will need a box spring, slats or even a plywood (or similar) base to set the mattress on. The rails themselves are good quality.

No, you do not need a box spring. I have my mattress on a plain plywood board, and it works great.

You don't need a box spring. This is the main purpose of this frame. It's surface is well supported just to hold the mattress w/o a box spring. Also, floor to the top of the frame is 14 inches. For me it will be too high if you put both box spring and mattress and will look ugly. But if you really want to put a box spring, of course you can put it. Frame doesn't have raised edges, so you can put anything on it. Also as the frame doesn't have raised edges, mattress tends to move on it. This will be a real problem if you have a box spring on it as resistance will be even less.
