A model described as a double frequently opens to a surface narrower than the standard UK double mattress of 135 cm by 190 cm, because the mechanism must fold a mattress inside a seat. This 2026 report compares the sleeping surfaces produced by chair beds, two and three seater fold outs, click clack designs and corner sofa beds against standard UK mattress widths of 90 cm, 120 cm, 135 cm and 150 cm. The measurement that really decides whether a sofa bed fits is the open footprint, typically 190 cm to 220 cm from the back frame, plus a 55 cm route on one side. Comfort depends on mattress depth and base construction rather than the sofa itself, and non standard sleeping dimensions make bedding a purchase to plan in advance."}
