A stroller wheel assembly has a wheel mount with an interior cavity and defining a generally vertical housing axis. An axle is carried by the wheel mount and a wheel is carried on the axle and rotatable about a rolling axis oriented perpendicular to the housing axis. A leg of a stroller frame has an end section coupled to the wheel mount. A suspension spring has one end borne against a spring stop on the wheel mount within the interior cavity and an opposite end borne against a fixed stop. The spring resiliently supports the wheel mount for movement against a bias force and by the bias force of the spring relative to the leg along the housing axis. The wheel assembly can also be capable of swiveling about the housing axis relative to the leg.
