| Measurement | What to record | Why it matters |
|---|---|---|
| Room height. | Measure finished floor to finished ceiling at several points across the proposed bed location. | Older floors, ceilings and local changes may produce a lower usable height than the headline measurement. |
| Frame height. | Use the latest drawing for the exact model, including posts, rails, curtain frames and attachments. | Triple bunk models differ substantially in overall height and cannot be assessed from a generic category figure. |
| Upper sleeping level. | Confirm the upper bed-base level and the top surface of a mattress no more than 200 mm deep. | Usable headroom is measured from the occupied mattress surface rather than the bed frame alone. |
| Ceiling features. | Map beams, slopes, lights, detectors, sprinklers, pipes, ducts, windows and access panels. | Local obstructions can reduce clearance or create conflicts even when the room height appears sufficient. |
| Surrounding access. | Check ladder approaches, circulation, doors, windows, maintenance access and the room fire strategy. | A bed that fits vertically may still be unsuitable for safe access or the wider room layout. |

Record finished height across the complete bed position, including slopes, beams and suspended features.

Use the latest model drawing and include every rail, attachment and selected privacy option.

Calculate upper-tier headroom from the specified mattress surface, not from the frame height alone.
| Planning example | Published product information | Project decision |
|---|---|---|
| Morpheus and Military. | Morpheus is 2066 mm high and Military is 2080 mm high; both require approximately 2400 to 2500 mm room height. | Use these low-profile options only after checking the exact external dimensions, ceiling features and mattress specification. |
| Repose with curtains. | The 2066 mm base frame plus 525 mm curtain structure gives a complete installed height of 2591 mm. | Provide a minimum room height of approximately 2900 to 3000 mm and verify access around the curtain structure. |
| Barracks Triple Bunk Bed. | The 2570 mm frame is available in 2 ft 6 in and 3 ft widths. | Provide approximately 3000 mm room height and confirm the selected mattress sizes and surrounding access. |
| Community Triple Bunk Bed. | The frame is approximately 2800 mm high and is available in 2 ft 6 in and 3 ft widths. | Provide approximately 3000 to 3100 mm room height and check the exact project configuration. |
| Hostel Triple with curtains. | The complete curtain-equipped frame is approximately 2820 mm high and accepts 2 ft 6 in to 3 ft mattresses. | Provide approximately 3200 mm room height and verify the highest installed curtain component. |
