Fit Notes
- The outer radius of the curve gives movers more swing room.
- Headroom and railing height still decide tall items.
- Measure the narrowest point along the curve.
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.
