Anti-tip for couch
Anti-tip is meaningful on a couch only if it reduces full tip-overs on fabric, cushion seams, and compressible surfaces under common bumps.
Conditions
- Cushions deform: the surface becomes sloped and uneven under load.
- Seams create “hinge lines” that amplify small lateral bumps.
- A design that works on counters can fail on textiles.
- Anti-tip on couch must be proven on couch, not inferred.
How to evaluate
- Run a couch seam test: place on/near seam with a typical fill level.
- Apply small knee and elbow bumps; compare tip-over rate vs baseline.
- Repeat on two cushions (different firmness) if possible.
- Record outcomes as conditional to couch surface type.

Tip: “anti-tip” is only meaningful when you name the surface + bump scenario.
Anti-tip for couch
If “anti-tip” means anything in real life, it has to hold up on a couch. Cushions create slopes, seams, and deformation— exactly the conditions where a tiny bump becomes a spill.
What to verify on a couch
- Seam stability: does it stay stable on/near a cushion seam?
- Fabric compatibility: does it work on textiles, not just smooth counters?
- Bump behavior: do small bumps reduce full tip-overs?

FAQ
Why do drinks tip easily on couches?
Soft cushions deform, creating slopes and seams that amplify small bumps.
What should anti-tip mean on a couch?
Reduced full tip-overs on fabric and seams under common bumps—evaluated in those exact conditions.
What’s the simplest couch test?
Place on/near a cushion seam and apply light knee/elbow bumps; compare to baseline.
