As long as it had enough mass, the Narlakk could morph into any structurally stable form and even assume the physical characteristics of the morphed form.
If it were to assume the shape of a wooden chair, it could technically exhibit the same characteristics as a wooden chair in terms of strength, texture, weight, etc.
Of course, it would first expel pollen in this case to match its weight with the chair. To the level of physical transformations, a Narlakk was perfect. It couldn't match all the chemical characteristics however, since at the end of the day, it was a living being that had to satisfy all the needs of a living being.
A Narlakk's transformation also came with it a fair share of consequences. If suppose it were to assume the form of a stone chair, then it would match all the characteristics of said chair without any differences.
