Kmart offers the First Act Adam Levine Drum Seat, model no. AL055, for $9.99.. Choose free in-store pickup to dodge the $8.99 shipping fee. (Note that pickup availability varies by ZIP code.) That's $30 off and the lowest price we could find for any rock star-endorsed sitting apparatus. Sales tax is added where applicable. It features adjustable height. While this stool will not bring you any closer to being a member of Maroon 5, you could sit on it to evaluate singers. (It's unclear whether it spins like the judges' chairs on The Voice.)

Update: It's now available for in-store pickup only.
