Triple Bunk Beds
A triple bunk bed places three berths in the footprint of one, which is why it is used in high-density dormitories, detention facilities and seasonal worker housing. Zehao builds these on a heavy-gauge welded steel frame, SGS tested to 200 kg per berth, because the leverage on a three-tier frame is greater than on a standard two-tier bed.

When a triple bunk is the right choice
- Use three-tier only where ceiling height allows safe head clearance on all three berths.
- Specify a welded or bolted frame with anti-tip anchoring; a three-tier frame carries more leverage than a two-tier one.
- Check the local rule. Some institutional buyers cap sleeping height or require specific guardrail dimensions.
- Plan the room around the bed, not the bed around the room - locker and desk placement drive the final layout.
Typical applications
- Prisons and correctional facilities
- High-density worker dormitories
- Seasonal labour housing
- Emergency accommodation
- Refugee and humanitarian shelters
