What size steel bed frame do I need?

We size the frame to the mattress, so give us its actual dimensions, for example 160 x 200 cm. Our loft platform bed for that mattress measures 1660 x 2060 mm overall, which shows how much space the frame itself adds. We make beds for mattresses from 90 to 200 cm wide, including non-standard lengths, and confirm the overall dimensions before production so the bed fits your bedroom as planned.
