What to look for
Work out what's actually shaking the floor
Two different problems get called "vibration." One is your kick pedal and kit legs punching low frequencies straight into the floorboards; the other is a subwoofer or monitor speaker doing the same thing while you play along to tracks. Those need different products, so decide which one is your issue before you buy anything.
Decoupling beats "thick"
A pad helps by separating the gear from the floor with something springy, not by being heavy. That's why foam-and-rubber platforms show up here instead of a plain slab. A thin dense mat can protect the floor and stop things sliding, but it won't do much for low-frequency thump on its own.
Foam-only vs a wood-cored platform
All-foam pads are cheaper and fine under a light speaker, but they compress and feel soft under load. A board core (MDF or plywood) over foam stays flat, so heavy gear doesn't sink in and tilt. If the item is heavy or you'll be nudging it around, pay for the rigid version.
Load rating and footprint, checked against your real gear
Load ratings vary a lot between pads — a pair of small monitors is a different job from one 10-inch sub. Measure the base of what you're lifting and compare it to the platform dimensions, because overhang on a foam pad defeats the point. Also note whether you get one pad or two; a stereo pair needs two.
Added height changes your setup
Every one of these lifts something by a couple of inches, and that moves your geometry. A 2-inch bass drum lift changes where the beater strikes the head, and a 2.5-inch platform under a desk monitor changes where it points. Expect to re-adjust your throne, pedal, or speaker angle afterward, and check the lift is worth that hassle.
