Note 6 — Chapter XXX · THE SRATAPARNA CAVE, OR CAVE OF THE FIRST COUNCIL. LEGENDS. SUICIDE OF A BHIKSHU.
James Legge translation
(6) Instead of “high” seats, the Chinese texts have “vacant.” The character for “prepared” denotes “spread;”—they were carpeted; perhaps, both cushioned and carpeted, being rugs spread on the ground, raised higher than the other places for seats.
