Bunk Bed Mattress Size
What size mattress fits a bunk bed
A standard bunk bed takes a single (twin) mattress about 90-100 cm wide and 190-200 cm long. Zehao dormitory beds use a 90 x 190 cm or 100 x 200 cm sleeping surface, and our standard dormitory mattress is 10 cm thick, 28 kg/m3 density, with an optional PVC cover.

Direct answers
What is the standard bunk bed mattress size?
A single (twin) mattress: 90-100 cm wide by 190-200 cm long. Confirm the exact sleeping surface with the bed model; Zehao bunks use 90x190 cm or 100x200 cm.
How thick should a bunk bed mattress be?
For safety, keep thickness within the bed maker and standard limit so the guardrail stays effective. Zehao dormitory mattresses are 10 cm thick, 28 kg/m3 density, with an optional PVC cover.
Can I use a thicker home mattress?
Only if it keeps the top-of-mattress below the guardrail minimum defined by EN 747-1:2024. Over-thick mattresses reduce guardrail height and are unsafe on the upper bunk.
Do you supply mattresses with the beds?
Yes. We supply matching dormitory mattresses (10 cm, 28 kg/m3, optional PVC cover) so the bed and mattress are certified together and ship in the same container.
What mattress size for a triple bunk?
Each berth uses the same single (twin) size as above; the stacked or side format only changes frame layout, not the sleeping surface.
Why mattress spec matters for bulk buyers
Ordering the wrong size strands a whole dorm. Specifying the sleeping surface and thickness up front lets Zehao pack beds and mattresses together, cutting a second shipment.
