Seat with a flipping footrest assembly

A seat with a flipping footrest assembly comprising:

• a cushion, a front surface of the cushion being a convex surface;
• a seat back mounted on a rear surface of the cushion and extending upwardly;
• and
• a footrest assembly pivotally mounted on the front surface of the cushion, being capable of pivoting up and down relative to the cushion, and comprising
• a first footrest pivotally mounted on the front surface of the cushion and being capable of pivoting up and down relative to the cushion, a rear surface of the first footrest being adjacent to the front surface of the cushion and being a concave surface, the rear surface of the first footrest corresponding in shape to the front surface of the cushion, wherein when the first footrest pivots up and down relative to the cushion, the rear surface of the first footrest, which is concave, moves along the front surface of the cushion, which is convex;
• and
• a second footrest pivotally mounted on the first footrest and being capable of pivoting up and down relative to the first footrest;
• wherein the footrest assembly further comprises a folded condition, a partially expanded condition, and an expanded condition:
• in the folded condition, the first footrest pivots relative to the cushion and pivots to a position below the cushion, the second footrest pivots relative to the first footrest and pivots to a rear end of the first footrest;
• in the partially expanded condition, the first footrest pivots relative to the cushion and pivots to a front end of the cushion, the rear surface of the first footrest is disposed close to the front surface of the cushion, so from a side view, an extended surface of a top surface of the first footrest and a top surface of the cushion jointly form a continuous and smooth line, and the second footrest is disposed to a position below the first footrest;
• in the expanded condition, the second footrest pivots relative to the first footrest and pivots to a front end of the first footrest, so the top surface of the first footrest and a top surface of the second footrest jointly form a continuous surface, and the second footrest, the first footrest and the cushion are disposed sequentially from front to rear.
