Fit Notes
- This is much tighter than a U-shaped stair with a real landing.
- Items cannot be set down flat during the turn.
- Check the outside walking line, not just wall-to-wall width.
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.
Washer or dryer
Only practical with appliance straps and enough outside-radius clearance.
Upright piano
Weight, balance, and landing turns usually require professional movers or another route.
