wherein the seat back comprises a first frame engaging portion,
wherein the upper seat member comprises a first seat engaging portion engageable with the first frame engaging portion, and
wherein the seat back further comprises a first resilient constraining portion being positioned to abut against the first seat engaging portion to constrain relative motion between the seat back and the upper seat member.
2 . The seat of claim 1 , wherein the seat hub is configured to allow the upper seat member to rotate relative to the stroller frame during the folding of the stroller frame.

4 . The seat of claim 1 , wherein the seat body comprises a second frame engaging portion engageable with the lower seat member.
5 . The seat of claim 4 , wherein the seat body further comprises a second resilient constraining portion being positioned to abut against the lower seat member to constrain relative motion between the seat body and the lower seat member.
6 . The seat of claim 5 , wherein the second resilient constraining portion is transitionable between a locked position in which the second resilient constraining portion abuts against a second seat engaging portion, and an unlocked position in which a second resilient constraining member allows relative motion between the seat body and the lower seat member.
7 . A stroller, comprising:
a stroller frame;
a seat frame, comprising:
a seat hub detachably connectable to the stroller frame,
an upper seat member extending from the seat hub in a first direction, and
a lower seat member extending from the seat hub in a second direction that is different than the first direction; and
a supporting unit including a seat back and a seat body, the seat back being detachably connectable to the upper seat member, and the seat body being detachable connectable to the lower seat member.
8 . The stroller of claim 7 , wherein the supporting unit is a first supporting unit, the stroller further comprising:
a second supporting unit detachably connectable to the seat frame,
wherein the second supporting unit comprises an infant carrier.
9 . The stroller of claim 8 , wherein the stroller frame comprises two sections capable of being folded and unfolded relative to each other and wherein the seat hub is detachably connectable to one of the two sections.
10 . The stroller of claim 8 , wherein the second supporting unit includes a first frame engaging portion engageable with the upper seat member.
11 . The stroller of claim 9 , wherein the second supporting unit further includes a second frame engaging portion engageable with the seat hub.
12 . The stroller of claim 10 , wherein the first frame engaging portion is directly engageable with the upper seat member.
13 . A seat frame for a child stroller, the seat frame configured to hold a supporting unit having a seat back and a seat body rotatably coupled to one another, comprising:
a seat hub;
an upper seat member extending from the seat hub, the upper seat member being detachably and slidably connectable to the seat back and connected to the seat body; and
a lower seat member extending from the seat hub, the lower seat member being detachably connectable to the seat back so that, when the seat frame is coupled to a frame of the stroller, a folding of the stroller frame unfolds the seat back from the seat body.
14 . A seat for a child stroller, comprising:
a supporting unit including a seat back and a seat body; and
a seat frame configured to hold the supporting unit, the seat frame comprising:
a seat hub,
an upper seat member extending from the seat hub, the upper seat member being connectable to the seat back, and
a lower seat member extending from the seat hub, the lower seat member being detachably connectable to the seat body,
wherein the seat back comprises a first frame engaging portion,
wherein the upper seat member comprises a first seat engaging portion engageable with the first frame engaging portion, and
wherein the seat back further comprises a first resilient constraining portion being positioned to abut against the first seat engaging portion to constrain relative motion between the seat back and the upper seat member.
15 . The seat of claim 14 , wherein the first resilient constraining portion is transitionable between a locked position in which the first resilient constraining portion abuts against the first seat engaging portion, and an unlocked position in which a first resilient constraining member allows relative motion between the seat back and the upper seat member.
