EXHIBIT 99.1

On August 17, 2009, the reporting person settled a prepaid variable forward
sale contract that was entered into on February 15, 2007 with an unaffiliated
third party purchaser.  The contract obligated the reporting person to deliver
to the purchaser up to 75,000 shares of Knoll, Inc. common stock (or, at the
election of the reporting person, an equivalent amount of cash based on the
market price of Knoll, Inc. common stock at the time of settlement) on the
maturity date of the contract (August 17, 2009).  In exchange for assuming
this obligation, the reporting person received a cash payment of approximately
$1,469,064.19 as of the date of entering into the contract.  The reporting
person pledged 75,000 shares of Knoll, Inc. common stock (the "Pledged
Shares") to secure his obligation under the contract.  The reporting person
also retained voting rights in the Pledged Shares and rights to receive all
regular quarterly dividends up to $0.11 per share per quarter declared on the
Pledged Shares during the term of the pledge.  The contract provided that the
number of shares of Knoll, Inc. common stock to be delivered to the purchaser
on the maturity date was to be determined as follows: (a) if the closing price
of Knoll, Inc. common stock on the maturity date (the "Settlement Price") was
less than or equal to $23.1805 (the "Initial Share Price"), the reporting
person would deliver to the purchaser all of the Pledged Shares; (b) if the
Settlement Price was between the Initial Share Price up to and including
$27.8166 (the "Cap Price"), the reporting person would deliver to the
Purchaser a number of shares of Knoll, Inc. common stock having a value
(based on the Settlement Price) equal to $1,738,537.50; and (c) if the
Settlement Price was greater than the Cap Price, the reporting person would
deliver to the purchaser all of the Pledged Shares, except a number of
shares equal to $347,707.50 (based on the Settlement Price).  On August 17,
2009, the Settlement Price was $9.10.  Accordingly, the reporting person
transferred to the purchaser all of the 75,000 Pledged Shares.
