Are castors chosen per piece or per order?

Per position: the same order can mix fixed sofas and mobile seats, because the base is declared in both variants across the whole family — each line of the list states its own choice.

Can the ottoman work as a side table?

It is declared as a seat, fully upholstered like the rest of the family. For trays and laptops the right tool is a side table from another collection — we can pair one in the quotation.

Do the chairs stack for events?

Stacking is not declared for Saari. For event halls that clear overnight we would point to other series, keeping Saari for the permanent soft areas.

Does Saari suit co-working common areas?

Yes — common areas are among the declared settings: armchairs and ottomans furnish the shared corners, the sofas anchor the break-out zones, and the chair follows into meeting rooms.
