The model for the bed in the bedrock edition of Minecraft has issues. The bed legs appear too wide and the pixels stretch, not matching up with the upper part of the bed. This causes the textures to overlap and glitch, and is more noticable in HD resource packs.

I have attached screenshots of both the Java and Bedrock editions of Minecraft, showing the vanilla texture pack and the Firewolf texture pack. The model of the bed in the Java edition is working and there is no texture overlapping.
