Hey folks! I'm building a floating desk that's 190cm long and 50cm wide, made entirely from 1.8cm plywood. This desk will need to hold a hefty 88-key electric piano weighing about 12kg along with some audio gear. I'm a bit anxious about its stability since I'm planning to pull the keyboard out from a drawer and will be applying some pressure while playing.
I live in an apartment in Germany, and my walls seem to be a mix of plaster and stone blocks, not drywall, so I'm not too concerned about studs. I initially thought I could use suspension rails with screws and Fischer DuoPower anchors. However, I saw a video suggesting lag bolts for mounting a smaller desk, which seemed much sturdier. Now I'm second-guessing my entire plan! Should I rely on the suspension rail method, switch to lag bolts, or maybe ditch the floating desk idea entirely and add some brackets for extra support? Any advice would really help!

Honestly, I think a floating desk this deep might be pushing it for safety. The leverage you create, especially with the keyboard on the edge, can really increase the stress on the attachment points. You might want to consider adding some brackets underneath to provide extra support. It might not be the sleekest solution, but safety is key!

Thanks for your input! Would adding brackets seriously improve stability?
