Dear valued relation,

As you know, Prooff introduced the EarChair by Jurgen Bey in 2006 as one of the first iconic furniture pieces for ‘The Progressive Office,’ followed in 2009 by the unique SitTable by Ben van Berkel (UN-Studio).
Step by step, Prooff developed several more innovative pieces of furniture designed by architects and designers, which are still relevant and widely used in office and work environments in 2025.

At the start of 2025, we conducted a thorough inventory of the storage and showroom stock of the Prooff collection. During this process, we discovered various Prooff models that were still in good condition and had been used in (international) trade fairs and showroom presentations.

We have now photographed all these furniture pieces, and they are available—at discounted prices—on the ‘Showroom Sale’ page of the Prooff website. With discounts of up to 70%, we are offering you unique Prooff furniture pieces at exceptionally attractive prices.

Additionally, we have temporarily displayed almost all Prooff occasion furniture in our showroom at Terbregse Rechter Rottekade 137 in Rotterdam.

If you are interested and would like to see the Prooff furniture models in person, please schedule an appointment here.
You are most welcome!

Best regards,
Leo Schouten
