Best idea is to move the hell out of there 🏃‍♂️🏢

If the building isn’t solid enough already to isolate noise and prevent shaking, then there’s little that you can do.

Dampers like those used for washing machines for your bed and while you are at it maybe put some gasket or nitrile tape in between your neighbours door as well.

Maybe obvious, but have you tried to talk to the neighbor?

In my previous apartment I had a shitty door that was hard to close without slamming it, and I didn’t realize how much it disrupted my neighbors when I slammed it to close it. Instead I started to turn the lock while closing it, which worked perfectly.

creative solutions

what about a hammock? or hang your bed on chains from the roof.

You can 3D-print guns now

Is the door that is being slammed a common door (like in the common hallway) you have access to? If so, install a damper on the door so it slowly closes. The more he pushes, the more it fights him.

If yiu don’t have access to the door, then get anti vibration levelers for your bed. There are lots of different ones. Some go under the existing leveler feet, while others would replace the leveler feet altogether so just make sure the thread is the same size. The rubber that these vibration isolators use varies in hardness. It might take some experimenting but you want a rubber that is soft enough that it compresses some when the weight of the bed and you are on it, but not so soft that it bottoms out.

Have you complained to the supervisor’s office yet?

They might care if enough people complain and evict the guy.

You may need a lower bed frame or none at all.

Compression springs on the feet plus the anti vibration pads? I’m thinking something like these but with sturdier springs. Or these but possibly less hardcore

Edit: obviously make sure the bed doesn’t rest against the wall too, but he’ll, if you have to, put springs there too!

If you have access to the door, even briefly, there are transparent sprays that make a coat of rubber like substance on stuff

Get it in the crqck of the door, near the joints and around them

I think this is one

Maybe try making bed slams shake your doors.

I’m already tried most all suggestions. Bed away from wall, low bed frame, made of wood, not metal, anti vibration pads. This is an old apt filled with addicts, mental health issues. No job, on ssi, can’t move, unless I want to be homeless again. Trying to make what I have works. Only response I got, haven’t tried, was platform on springs, rollers. Tks to everyone.

Oh, talking to neighbor, landlords, not applicable. Cops, screaming, fights breaking out, meth heads, everyone smoking cigs in their apartments… someone with anger issues simply slamming doors … it can be so much worse. Trying to cope best I can

Have you tried moving your bed away from the wall? Or even to the opposite side from where the door is?

I feel for you. I have shitty neighbors too.

Man that really sucks.

I’m guessing that it’s not reasonable to get the guy to chill or get the builsing tuned up so that it doesn’t transmit so much vibration.

The “ideal” wouls be a platform that can move laterally (and a little vertically) but that damps the vibration. Imagine a platform the bed sits on, but with springs below it. Or something fancier that acts like a spring but uses another mechanism. This way, the bed will move less initially (the floor will move and the bed will have to “catch up” based on the weaker + delayed pull of the spring) ans be damped.

Keep in mind that I haven’t tested any of this, but here are a couple ideas.

1. Casters/rollers, each of them on a little square (maybe silicon?) that keeps them from rolling too far. This will have weak lateral damping ans probably zero vertical. Imagine something like this but you actually buy one larger than specified so it can still move a bit: https://www.amazon.com/Yupeak-Bed-Stopper-Furniture-Pack（Black）/dp/B07MPR999F/

2. Put a box spring under your mattress and literally attach springs on the bottom and sides so that it only contacts your bed frame / floor (not sure what your setup is) via springs. Strong springs so that they don’t bottom out when you lay on the bed but not so strong that they don’t damp enough. Probably bed springs, basically.

3. A second soft mattress to put under your mattress. It’s basically just a set of springs and is already the right size. This is probably the best option.

Also, if your bed is next to the wall, move it 2-3 inches away from it.

Hope this helps!
