Ledge™ Folding Lap Tray

There is nowhere to put the mug. The coffee table is out of reach from where you sit and the arm of the sofa is rounded and upholstered, so the mug ends up balanced on a cushion, wedged between your thigh and the armrest, or on the floor where someone will kick it. You have already cleaned coffee out of that cushion once.

Ledge™ gives the arm a flat top. Two slim bamboo legs are hinged underneath on metal pivots and swing down and inward, so their own weight and the weight of the tray clamp it to the armrest and hold it level. Nothing screws in, nothing clips on and nothing marks the fabric. It sits astride the arm as a bicycle saddle sits on its post, and it lifts off in one movement when you want the arm back.

The face of the tray is 25 cm across, with a raised lip all the way round, and the lip is the important part: a flat board on a sofa arm lets things slide to the floor, and the lip stops a mug moving when someone sits down heavily next to you. It has room for a mug, a phone, the remote and a paperback together. Because it is solid bamboo and not veneered board, the rim can be a single continuous curve with no seam to lift, and wiping does not make it swell.

It fits most standard upholstered arms of sofas and armchairs, about 10–20 cm wide, flat on top or gently rounded. When it is not in use the legs fold against the underside and it lies flat, in a drawer, behind the sofa or on the coffee table as a small serving tray.

Wipe it with a damp cloth and dry it at once. Never soak it or put it in a dishwasher, and do not leave liquid standing in the tray overnight, because bamboo is laminated in strips and prolonged wet is the one thing that lifts a glue line. Mop up spills when they happen. If the surface looks dry or pale after a year, rub in a thin coat of food-safe mineral oil with a cloth and buff it off to bring back the colour. Do not put a hot pan or an uninsulated cafetière straight onto it, and check the pivot rivets now and then: if a leg feels loose, a gentle squeeze on the rivet head with pliers takes out the play.

Solid laminated bamboo throughout, sanded and sealed clear, with two hinged bamboo clamp legs on steel pivot rivets. Verified size from the manufacturer's own dimension drawing: the tray is 9.84 in / 25 cm across the face, with a raised rim lip about 1.5 cm high and an overall span of about 10 in / 25.5 cm with the legs folded down. It weighs about 420 g. There is no plastic, no veneer and no adhesive-backed pad; the grip comes from the shape of the legs and not from a rubber surface that would eventually mark upholstery.
