A mattress clip to secure the fabric flange of a mattress cover to adjacent springs of the innerspring assembly, such clip having a hook end, a short lateral leg extending therefrom to an integrally formed single loop having a narrow but resiliently expandable entrance to receive and hold the ring of an adjacent coil spring therein, a longitudinal leg extending therefrom to an integrally formed double loop, a return longitudinal leg extending therefrom to terminate in a sharply pointed end adjacent the hook for reception therein after the return longitudinal leg with the sharply pointed end has been passed through the fabric flange of the mattress cover. Such clips enable an end use customer to assemble a mattress from component parts, including the innerspring assembly, then placing insulating and cushioning pads thereon which are secured to the springs by the mattress clips, finally placing the outer mattress cover with fabric flange over the insulating and cushioning pads and securing such flange to the springs by the mattress clips. The peripheral border strip is then secured around the peripheral side wall of the mattress by a zipper assembly or hook and loop fastener strips around the upper and lower peripheral edges of the border strip, or by a zipper assembly or hook and loop fastener strips around one of such peripheral edges and by permanently securing the other peripheral edge to the adjacent peripheral edge of the mattress cover.
