Our take on the West Elm Harris Twin Sleeper Sofa

The Harris is a classic-roll-arm sleeper sofa from West Elm, hand-built in the USA on a kiln-dried hardwood frame with mortise-and-tenon joinery and sinuous spring support. It folds out to a queen gel-foam mattress with a breathable knit ticking, and the seat cushions are fiber-wrapped high-resiliency foam at medium firmness. Upholstery comes in top-grain leather or vegan leather, and the piece is contract grade, so it is built for commercial use as well as a home. It suits guest rooms and dual-use living spaces where the sofa has to look good and sleep someone; against cheaper sleepers, the gel mattress and hardwood frame are the main step up, while the loose, non-reversible cushions and plastic legs are the trade-offs.

About the West Elm Harris Twin Sleeper Sofa

The Harris Sleeper Sofa is a classic-style sofa that unfolds to reveal a Queen-sized pull-out mattress. The gel mattress has two layers, high-density foam and gel-infused foam. It is designed to contour to the body and wick away body heat. The mattress ticking is a soft, breathable knit.

The frame is hand-built from kiln-dried wood, which helps prevent warping, and has mortise and tenon joinery. The upholstery is hand-finished. Support comes from high-gauge sinuous springs and webbed cushion support. The cushions have fiber-wrapped, high-resiliency polyurethane foam cores with zip-off covers. Seat firmness is medium, a 3 on a scale of 1 to 5, where 5 is firmest.

It is assembled in the USA and made in a choice of color and fabric. It is contract grade, built for commercial use as well as residential use. To avoid damaging the frame, do not fold the mattress into the sofa with sheets or blankets on it.
