Fit Notes
- No landing turn, so stair width and ceiling headroom are the main constraints.
- Railings can reduce usable width by 3 to 4 inches on each side.
- Long rigid items can usually be tilted along the stair slope.
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.
Folded treadmill
Remove console parts when possible and check landing swing clearance.
Upright piano
Weight, balance, and landing turns usually require professional movers or another route.
