How to Measure Up for Chair Beds: A Simple Sizing Guide

Measuring up for a chair bed is simpler than it looks once you know which figures matter. You need the closed footprint of the chair, the full open length when the bed is extended and the clear width of every doorway, landing and stair turn on the way into the room. In this guide we explain how to mark both footprints on the floor, how much clearance to leave around the open bed and how to check whether the chair will pass through older UK doorways and staircases. We also look at sleeping length for taller guests, the depth added by the mattress and how to place a chair bed in a box room, living room, home office or landing without blocking doors, radiators or escape routes. A practical checklist at the end keeps every measurement in one place, so you can compare designs quickly and choose a chair bed that fits your room in both positions....
