What do you want to get from the speakers? I think a lot of the change in sound from stands is due to the shape of them, not how super steady they are or if they have spikes or whatever. Although clearly you don't want a big resonating panel.
A stand with a big solid area on the front will effectively extend the speakers baffle and boost the lower mid giving a more meaty full sound. An open frame stand will give a thinner faster sound by not boosting the lower mid-band.
I don't think any 1m tall stand will be very stable, especially if your floor is like mine; thickly carpeted and not that flat anyway!
Edited to add, a stack of breeze-blocks can be pretty stable and make a superb stand, but I hope your floor is strong!!
