Can a king size mattress be put on this frame?

Yes, according to the manufacturer. Essentially, a king size frame is comprised of two twin xl frames, with a center attachment piece. I couldn't tell you if a single fixed king-sized bed frame was any stronger or better, than two PragmaBed frames connected together (as the manufacturer sells). If you have to know the answer or a scientific opinion, best check with an engineer regarding rigidity, surface / contact-point tension and flex, and weight issues between this and your other option (the engineer might really enjoy this study). Other than that, I haven't read anywhere where connecting two strong xl twin frames were anymore dangerous, or if it really mattered. My two cents. Yes, according to the manufacturer.

The queen size fits it perfectly. A king might be to big. An aside, I have been using this for some time now and it is great.

I was a slight bit upset about this frame, as it is truly a queen-sized platform. However, a full size bed will of course fit on it with room to spare around the edges, and a full set is what we currently have. However, I was fine with the frame as it was well constructed and will fit a queen if we so desire to switch over.

Yes, you can. You may eventually want to change it over to just the basic frame that's designed for it (because of height, the box springs wearing down, etc.), but it should be fine placed on the box springs.

The mattress wouldn't be flexible enough for a mattress at least for putting it in the seated position. The mattress should be a futon mattress for your best use of the frame.

Yes. We have our king size setup with the existing king box spring for our old mattress. Most comfortable bed we have ever had!

Hi Colleen: This frame is for a California King sized mattress which is slightly less wide but longer than a regular king Mattress. It is not adjustable. Fantastic frame but you'd have to have a Cali King only.

A king-size mattress is a different size from a California king. So, the answer is 'no'.

They can definitely be pushed together, but I have no clue whether or not it would fit a king sized mattress. Do two Twin beds combine to form a King bed?

Yes..we have ours in front of a king size..it is not the same height of the bed.

You must have meant a king size bed frame. That is pretty much what I did with this item. I connected a full size headboard to a queen size bed frame. This item allowed me to use the original bolts and nuts to attach it to both the bed fame and the headboard. It isn't real sturdy this way but it works fine for aesthetic purposes.

I believe, you would have to buy a bed frame for a twin bed. I bought a Twin XL for my grandson's Twin Xl mattress... You might be able to get 2 twins from a King size one.

Not to be pedantic or anything, but I would think a California king mattress would fit a California king frame. It seems like not much else would fit it.

I don't see why not. We use it with a memory foam mattress. It also comes with a covering. We sit ours on a solid 9 point metal frame. Then cover it with a bed skirt. Our box frame is king size, so carrying into our bedroom unassembled was a plus. It is pretty solid and quiet. I used extra screws to anchor all the cross boards in place to make it as solid as possible. They only give you a minimal amount of screws from the factory. Easy fix

If they are the standard 38" wide, yes, they will fit into a King frame. http://www.beddingexperts.com/mattress-sizes-chart/

This comes as two separate peices that when put together make a king frame. It fits king mattress with no spare room. I would measure the width/length of the king bed and compare it to the width/ length of the frame. If you have 3 inches to spare it should fit. It's a very sturdy frame. Plus Amaxon has a great return policy!

I'm not really sure if that will work or not. From what I remember from putting it togther the side board and foot boards should allow any standard King size box spring. I think I would contact the company directly to ask before you purchase to be on the safe side

I can only speak for the Queen-size frame. I say, Definitely Not. The frame is very strong and has plenty of support. All box springs already have plenty of cross slats. If you are putting the mattress directly onto the frame, you definitely need some more cross slats, or better yet, 3/4" plywood.
