Fit Notes
- Width is often better than residential stairs, but repeated landings still decide long-item pivots.
- Door openings into the stair shaft can become the bottleneck.
- Confirm building rules before moving furniture through stairwells.
What Fits?
3-seat couch
Often works if carried upright and the landing has enough pivot space.
Queen mattress
Usually clears on edge because thickness is the limiting dimension.
Appliance on dolly
Depends on landing depth and door swing.
Upright piano
Weight, balance, and landing turns usually require professional movers or another route.
