An L-shaped sofa is the family-living-room workhorse: seats 5-7 people in proper comfort, anchors the corner of an open-plan space, and gives one person a chaise to lounge on while the rest sit upright. The orientation matters more than the price; left-hand chaise vs right-hand chaise has to match how the room actually flows. Aosom UK, Cherry Lane Garden Centres and Choice Furniture Superstore between them cover £14-£6,449 across the range. Standard L-sofa sizes run 220x170cm (small living room), 270x180cm (household standard), and 320x200cm (large living rooms and family settings). Modular L-sofas reconfigure into a row, an L, or a U-shape, which suits households who move; fixed-frame L-sofas only do the L. Look for fabric protection (Scotchgard or similar) on family-use upholstery. Reversible chaise designs (the chaise-end works on either side) are the safer buy when the bigger picture isn't yet clear.
