A multi-flexure payload isolation device for isolating a payload from outside forces. The device can include a housing comprising an interior cavity configured to receive and support the payload. The device can further include a first flexure and a second flexure, each including a plurality of spokes made of a pseudoelastic shape-memory alloy anchored to the housing and configured to support the payload from the housing through an opening in the housing. The first and second flexures can each further include a common hub attached to a side of the payload and disposed in the opening in the housing wherein the each of the pluralities of spokes are anchored to the respective common hub.
