What do Tibetan Buddhists use for meditation cushions?

NAmaste Kabir, You do not need to copy any style of cushion in particular because meditation is about comfort, not the cushion itself. Tibetan Buddhists often use a round cushion called a zafu or sometimes just folded blankets to sit on. The idea is simply to raise the hips a little so that the back stays straight and the legs do not hurt. But I definitely suggest you to use Tibetan singing bowl during meditation. It is used for calming effect. Tibetan Buddhists also focus a lot on breathing and chanting mantras. You can also start with ''OM'' Chanting for 10 minutes everyday. So don’t worry too much about cushions. Start with what you already have.
