A wheeled walker with wheels that are at least seven inches in diameter while having a seat with its top surface less than 20 inches high and accommodating a full size basket by using an inverted "u" shaped lower cross member with spacers that cushion the basket. Spacers carried on a rear upper cross member cushion the seat. The basket includes a pair of opposing vertical wires of substantially greater thickness than adjacent vertical metal wires and which extend upwardly into hooks that support the basket on a front upper cross member. A tubular seat back bears a tubular cushion having a radius of curvature such that the rearmost depth is about 3 to 8 inches, preferably 4 to 7 inches, most preferably 6쩍 inches, and the arc angle is about 110 to 120 degrees, preferably about 112 to 116 degrees, most preferably about 114 degrees. The tubular seat back is carried on tubular members received in respective opposing tubular receptors, each having an aperture receiving a latch locking the seat back to front legs of the wheeled walker that is spring loaded to jut from the aperture and which is connected by a lever to a release button jutting from another aperture.
