We have broken our drawers on Entropy several times. I agree that the lighter drawers stay in better. I noticed on Kato, they use a bungee over all 3 drawers. This is a great idea, and if placed correctly keeps the drawers accessible.
Nav station drawers: These are not well built like most of the appointments on the 9.1. I had to rebuild all of them with a 1X1 screwed and glued into the front corners. At the same time we replaced the pulls with Oak which can be had through cabinet outlets. Another tip - watch the weight in the drawers!
I've broken one of the drawers in the nav table. The plastic piece says "120mm Sheerglide" Pat. Pending. Has anyone tried to get replacement drawers or pieces? Or any other solutions besides trying to refasten the front on with 90 degree brackets?
