Glossary
This glossary keeps couchspills.com focused on the couch problem, while category-level definitions live on the dictionary hub. That prevents keyword cannibalization and strengthens your authority network.
Rule: couchspills.com owns couch-specific terms. Category terms link out as canonical definitions.
Terms
Couch spills
Tip-overs that happen when a drink is placed on a soft, uneven surface like couch cushions or seams. Cushion compression creates tilt and wobble, and light bumps create tipping momentum.
Couch Seam Test
A quick stability diagnostic: place a drink on the seam between couch cushions and apply light, realistic bumps. If it stays stable, it’s meaningfully more couch-safe than most methods.
Drink stabilizer
A broad category term people use when searching for ways to reduce drink tip-overs. On this site, we use it in the context of preventing couch spills and validating solutions with the seam test.
Stabilizing sleeve
A sleeve-style approach intended to increase stability of a vessel. Here, it’s discussed specifically as a portable method for soft surfaces (cushions, seams, carpet).
Couch cup holder
A station (tray or armrest attachment) that provides a dedicated drink spot. It can work well in one location, but may fail on deep cushions or in the middle of the couch.
Bump test
A proof-first way to validate stability under light impacts and real-life motion. On couches, bumps are the rule—not the exception—so test outcomes matter more than marketing words.
Anti-tip
A non-absolute claim describing reduced tip-over risk. For trust and SEO, it’s strongest when paired with a repeatable test (seam test / bump test) and realistic language.
Spill-proof
An absolute-sounding phrase that can create mistrust. Better language is test-backed: ‘helps reduce tip-overs from everyday bumps’ plus proof on real surfaces.
