Lap trays

Lap trays are a great laptop tool. For drinks, they’re only safe when they stay level under cushion deformation.

When lap trays work for drinks

When they fail

Proof-first evaluation

Run the Couch Seam Test logic: if it fails on seams or under light seat shifts, it’s not couch-safe.

FAQ

Are lap trays safe for drinks?
Sometimes. Only if the tray is rigid, level, and stable on your cushion. Many lap trays tilt with cushion compression.
What’s the biggest risk?
Cushion tilt + posture shifts. The tray moves, then a small bump becomes a tip-over.
How do I test one quickly?
Place it over a seam area and apply light movement (seat shift). If the tray tilts or wobbles, it’s not couch-safe for drinks.
