I bought a K&M 18950 stand, and needed a way to carry it. The "official" bag 18959 is 40cm wider than this one and seems to have no padding.
For £13 less, this fits really nicely and has padding. I don't think the stand needs padding to protect it, but I do prefer to have padding to protect other things from the stand, which is angular and heavy! Be aware that the 18950 stand will need fully folding down to fit. If you prefer to leave the table and legs extended, a longer bag will ne necessary.
I haven't dragged the bag anywhere yet , but given the the thick nylon and my very positive experience with Thomann's other in-house bags, I think it would last many years.
