Really respect what you're going for here. I started out playing on 2 liter bottles filled with different amounts of water for different pitches until I could afford my first E-Kit. I'd recommend slowing down a bit and focusing on keeping tempo and practicing some rudiments if drums are something you want to get serious about. Keep it up though! Mattresses have almost no rebound so practicing like this can be really good for your power and speed once you move to a real kit.

Amazing!!

in less than 3 seconds I knew I'd like to play with you.

Bro you know that’s how Travis started out, on his bed

Good vibes cant wait till you get on some real drums!!

Very inspiring bro... Try to find how to practice the bass drum
