    Any suggestions and thoughts what would be a desent basstrap. I am thinking of a rectangular shape that could be hung on the wall or that has wheels. I think it would be made of rockwool. Is thicker always better?

    You want at least 4" thick OC703, 705 or rockwool. The standard panels come 2'x4' (but some may be a little undersized, so don't cut the wood until you have them to measure!) so the standard size of them is 2'x4'. 6" thick is even better, and 8" is the maxium you would typically need in a home studio environment, as they woudl take up more space and there might be better solutions (more 4" traps, for example).

    I think the terminology is not set in stone, but I think of "bass" traps as those big (thick, like @mjbphotos says) things that sit floor-to-ceiling in the corners, i.e., where the bass frequencies like to hang out and make trouble. Not generally something movable.

    If you want something movable (sometimes called or aka a GOBO) to provide some isolation between mics, e.g., when you're recording two people playing acoustic guitar in the same room, that's probably going to be thinner than a "bass" trap, and wider, and not ceiling height. The design will be determined kind of by how you plan to use it, and what recording scenarios you want to manage, as well as if you expect to keep them in place for, or in addition to, treatment of the room.

    I've got a couple of 3'x4' panels on legs about 1' tall just for the 2-acoustic guitar scenario. The stand on top of short "cubby" things from IKEA (decades ago) so act as wall treatment, though they're about 8" from the wall and not attached. I'm not a mechanical engineer and trying to figure out how to make them wall hangable will have some way to stand them up and not be easily tipped was beyond my ability or interest, TBH. Anyway, they do what I need. I think you'd find a panel of any (usable for mic isolation) size that didn't have some kind of wide bass attached or one it could perhaps snap into would be a hazard, and if the basE/wheel arrangement is wide enough, it's not going to hang nicely. Maybe some wheels brackets that could rotate in place to keep it narrow when hanging and then stable as a free-standing piece, but that gets complicated, heavy, and might add some rattly noises when hanging if you've got loud stuff to record.

    P.S. found some pics I posted here of my space - there's one of the homemade things in this set

    Just to unconfuse the OP, Keith meant BASE in the phrases above.

    These are what I consider *bass* trap sizes, though of course, you also have the more formal corner-specific designs that can be even bigger/beefier...but these are the ones I made for primarily bass management, and big enough that they will stand up on their own, though in busier studio environment I would opt for some additional support slats on the bottom...just some perpendicular crossbars/legs to make them even less prone to tipping, but they work fine as they are now, just not 100% tip-free.

    I'm assuming you are working with that room from a previous post.
    Looks like you a have some tri-corner nooks to work with.
    Could try grain sacks stuffed with dense cushions/pillows with some airspace behind.
