输入您的家具尺寸和走廊测量数据，检查U型转弯——走廊宽度、折返深度和倾斜策略。
Whether it fits comes down to the measurements most people skip.
Real openings run about 1 to 2 inches under the labeled size, and a single inch can flip the result. Check your own measurements before you buy or move.

Frequently asked
U型走廊由两条平行走廊和一段短折返段连接而成，形成U字形（180°方向改变）。常见于公寓楼、酒店式布局和多单元综合体。折返段是最紧的限制因素。
01将物品竖直倾斜以减少其在地面上的占地面积。让底部绕过内墙，同时顶部从上方的开放空间摆过去。对于很长的物品，您可能需要依次在U型的两个转角处转动。
02是的——U型转弯本质上是两个连续的90度转弯，中间有一段短连接段。物品必须完全反向，这需要比单个转角更大的操作空间。能通过L型转弯的物品可能无法通过U型转弯。
03长度超过折返深度两倍的物品通常无法通过。标准沙发（84"）、床垫（75–80"）和高书架（72–84"）是最常见的失败案例。书桌、抽屉柜和小桌子等较短物品通常能通过。
