Also, which one should I get the usual beads or bamboo one ?

No, the ones in the link you posted are not good. Please use the usual beads as per the picture posted by shyamhegde. They definitely help to ease back strain and stress....gives a sort of acupressure treatment while you are driving. Do remember to fix them taut on your seat.
