Practical Guidelines for Furniture Transportation
To help you determine in advance whether there is enough space to move furniture into your home, we provide practical guidelines illustrated with 3D diagrams and specific data for three transportation scenarios:
Stair Transport:
- Ensure that the narrowest point of the corridor is ≥1.8 meters.
- Corridor width should be ≥2 meters.
Residential Door Width:
- Must be >76 cm.
Elevator Transport:
- We recommend dimensions of >1.5 meters.
- Applicable sofa bed sizes (ranging from 120×190 cm to 180×200 cm) are indicated for three elevator specifications.
These guidelines offer a clear reference for transportation prerequisites, helping to avoid losses due to size issues.
