PROBLEM TO BE SOLVED: To provide a seat member and a seat, comfortable to sit on, and having both deformability and restrictive property in excellent balance.SOLUTION: A seat member 1 includes a seat core material 2 comprising an urethane-based resin foam molding having a space part 21, and a particle group 3 of foam particles 31 filled in the space part 21. A seat includes the seat member as a seat cushion, a seat back or the like. The space part 21 has a flow area 4 of the particle group 3 inside. Preferably, the ratio of a bulk volume of the particle group 3 to the whole internal volume of the space part 21 is 0.2-0.8.SELECTED DRAWING: Figure 2
