A morphable packer and method of setting the packer to anchor one tubular within another tubular or borehole, and create a seal across an annulus in a well bore. The packer is formed as a single tubular member having a central section between end sections. Undulations are formed on the tubular member to create recesses in which annular slips having oppositely arranged inclined surfaces and an outer gripping surface are located to provide an anchoring arrangement. When morphed the slips move uniformly radially outwards and anchor to an outer tubular. Embodiments include pairs of reversed slips located in the recess, pairs of anchoring arrangements located along the tubular member and a gasket seal arranged around the tubular member.
