Heavy-gauge carbon steel frame with folding backrest, 6 in front casters and 20 in solid rear tyres. Mesh cushion, ABS armrests, plastic footplates, four brakes. The 20 in wheel is the compromise format: narrow enough for domestic doorways and light enough for daily transfers, while retaining enough rear wheel for the user to self-propel. A side-guard version is available as LJ-402.
