what is the maximum thickness of the mattress that can go on top?

The top mattress can really be of any thickness because it doesn't have to roll underneath.

Depends on the thickness of the mattress. It's kind of hard to maneuver and the top bed is really high.

It hangs over about two inches on the side, I guess it depends on mattress thickness. Overall, I would not count on it to protect other than top.

I have this in the full size, and it covers the entire top and sides of the mattress. It is held in place with elastic at the corners. It's much thicker on the top than the sides.

There is only about 13 1/2 inches total from the slats where the mattress sits to the top of the highest board....so I would say a 12 inch mattress would not be safe. Our standard mattress is about 8 inches....I wouldn't go any thicker of a mattress than that.

Bottom sheet comes around to top of mattress and then the top sheet will fit

It is flat and just goes on top of the bed and not over and around the corners, so it will fit any thickness of mattress.

We have ours on a mattress. I think it's too thin for a total mattress. You need a 6 inch thick topper for that or buy two of these. It's not hard foam it's very soft so you will also need a base for it to sit on or it will fold into the grooves of the support boards on the bed.

The mattress is the full 8" thick-just took a tape measure to it to verify. FYI all futons and mattresses will lose height with use as you're compacting the material - that's why it's good to turn the mattress over and even rotate it end to end periodically to even out the normal wear. This particular futon mattress has an inner spring so it wears more evenly as weight is distributed better than with a non-inner spring futon. I've used futon mattesses for over 30 years and this one's my favorite. I ordered mine last summer - you may want to contact the seller and verify that it's the same product. Hope that helps.

10" will put it really close to the top of the rail. The paperwork says a max of 6". that is too thin to be comfortable in my opinion, so I added a couple slats (1x2s at home depot) and put on 8" mattresses. I wouldn't do 10" if I were you, unless your kiddo won't roll off- once you add the covers, there won't be much of a lip.

The mattress is extremely tall so I wouldn't put this on top of anything unless you want to use a step ladder to get on and off the bed.

You can use a box spring with the Sleep Master frame. However, since the top of the frame is 14 inches, it is already at the standard height of a frame and box spring, so putting a box spring on top would increase the height of your mattress by whatever the thickness of your box spring is. We tried it just to see how high it would be, and for us it was just too high.

The highest that I can get mine to click into place is 40" off of the floor. It raises a bit higher, but will not click into place. I have a very high bed and this bedfan raises high enough to reach above the mattress.

Hi, I have a tempur-pedic mattress on it which is quite thick. It's larger than the standard coil mattress in thickness. It reaches to to the bottom of the low section of the frame's arms.

I have a platform bed mattress which is 12 inches deep. I would not want anything thinner.

The mattress is medium thickness, but kind of hard and goes flat easily. I would honestly spend the money and get a better couch/futon. It's what I had to end up doing!

The side of the mattress is a different material than the top, so probably not. But the top is generous and goes all the way to the edge of the mattress. We're really happy with it.
