Fit Notes
- The 180 degree turn is the tightest checkpoint for long sofas and appliances.
- A square landing helps, but the item still needs vertical clearance to rotate.
- Low ceilings over the landing can block upright tilting.
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.
