FAQ

This sturdy black-framed bunk bed is specifically designed for space-efficient dormitory and multi-occupancy living environments. The bed measures 1900mm in length, 800mm in width, and 1800mm in overall height — fitting standard dormitory layouts while maximizing sleeping capacity. The lower bunk sits at approximately 450mm from the floor for easy access, while the upper bunk provides a generous 1100mm of headroom beneath, ensuring comfortable sitting posture. Each bed level is fitted with a 15mm thick plywood bed board supported by 4-5 steel cross beams. The robust frame is constructed from heavy-duty steel tubes: 40×40mm main posts (1.5mm wall thickness), 40×80mm side rails, and 30×50mm cross beams. The upper bunk features a 300mm high safety guardrail and a side-mounted ladder with anti-slip steps for secure climbing. All steel components undergo acid pickling and phosphating before being finished with black electrostatic powder coating for superior rust and scratch resistance. The bolt-together assembly system (no welding) allows for easy installation, disassembly, and relocation. With a total load capacity of ≥200kg, this bunk bed combines durability, safety, and space-saving functionality — making it the ideal choice for schools, employee housing, and camping facilities.

Applicable Scenarios
School dormitories, employee dormitories, apartments, campsites, and other multi-occupancy spaces

School Dormitories
The 800mm width fits standard student mattresses while leaving space for personal storage. The 300mm guardrail exceeds typical safety requirements, preventing nighttime falls. The sturdy black finish resists scratches from daily use and school cleaning schedules. The bolt-together design simplifies annual relocation for summer cleaning or room reassignments.

Employee & Worker Dormitories
The heavy-duty construction (≥200kg total capacity) accommodates adult workers and their belongings. The 1800mm height allows two bunks in a standard room without feeling cramped. Anti-slip ladder steps ensure safe climbing even during early morning or late night shifts. The rust-resistant coating stands up to industrial environments.

Youth Hostels & Campsites
The space-saving vertical design maximizes sleeping capacity in limited square footage. The 1900mm length comfortably fits standard hostel mattresses. The all-steel construction resists rough handling from multiple guests. The black powder-coated finish is easy to clean with disinfectant wipes between stays, and the bolt-together design allows for seasonal disassembly and storage when not in use.

Home Use (Kids' Rooms & Guest Rooms)
The 800mm width fits children's bedrooms and compact apartments. Parents appreciate the sturdy guardrail and non-slip ladder for children's safety. The neutral black finish matches various room décors. The 450mm lower bunk height allows young children to get in and out safely. The bed can later be separated into two single beds if needed (configuration dependent on model).

Q1: What mattress size fits this bunk bed?

The bed frame accommodates standard single mattresses measuring approximately 1900mm × 800mm × 80-120mm (thickness). We recommend checking the internal bed board dimensions (1890mm × 790mm) when selecting a mattress to ensure a snug fit.

Q2: Is the bed stable and does it wobble?

Yes. The bed is designed with a sturdy 40×40mm main post structure (1.5mm wall thickness) and 40×80mm side rails, plus 4-5 cross beams per level. High-strength 8.8-grade bolts with locking nuts secure all connections. The included leveling feet compensate for uneven floors, ensuring wobble-free stability.

Q3: Is the ladder included, and is it safe to climb?

Yes, a side-mounted ladder with 2-3 steps is included. The steps feature anti-slip tread patterns and the ladder is securely bolted to the main frame. The maximum recommended user weight for climbing is 120kg.
