What the wings actually do
Two things, and they work independently of each other. The practical one is lateral support: the wings give your head somewhere to go when it tips sideways, which is most people's default position for dozing in front of the television. Without them, your neck carries that weight on its own.
The second is about feel rather than function. The panels close off your peripheral vision a little and create a sense of being enclosed. Plenty of people find that settling, which is exactly why the design has lasted. Some find it restrictive. It's worth sitting in one if you've never tried it, because it's the sort of thing you either take to or you don't.
Push-back or power lift
Three of the five chairs are manual push-back. You lean into the backrest, your own weight opens the recline, and you sit forward again to close it. No lever, no cable, nothing electrical to fail. Have a look at the wider manual recliners range if that's the mechanism you're after.
The other two are power lift models operated by a handset. One direction reclines the backrest and raises the footrest. The other tilts the entire seat base forward at the front, raising the front edge of the seat. These need a plug socket within reach of where the chair sits. The full power lift recliners collection has more options.
Measuring before you order
Two numbers matter more than the footprint. Back height is the one people forget, because a wingback sits taller than a standard recliner and can cut awkwardly across a window sill or a dado rail. The other is the clearance behind the chair, usually 30 to 40cm, which the backrest needs in order to open fully. If it's going against a wall, measure that gap before anything else.
Where a wingback sits best
A wingback reads as a statement chair rather than a background one, so it tends to work best on its own: beside a fireplace, angled into a corner, or in a bay window. Matched pairs need a large room to look right. In a smaller living room, one wingback alongside a two-seat sofa usually sits better than two armchairs facing each other. The broader recliners range covers other shapes if the winged profile is too much for the space.
