Cyclohexane conformations can take several 3 dimension shapes. Of these, the most common ones are chair, half chair, boat, twist boat. The molecules can easily switch between these conformations. Half Chair conformations are least stable because carbon atoms at one end of the ring are planar.

the ring having planar structure has torsional as well as angular strain, whereas the boat conformation does not have these.
