Description

The TUB series welcomes two new highlights: a stool and a bench. Both items are real all-rounders, making the perfect seats and storage solutions in entrance areas and offering additional space for shoes. The stool also makes a striking nightstand or side table in bedrooms or elsewhere. The bench is equally versatile, offering plenty of surfaces to put things on.Creative individuality. A feature of the TUB product line is the taut interaction between right angles and curved surfaces. The result: a clear design statement, and of course maximum functional efficiency, interpreted in wood and style. The coat stand and console table have a solid wood frame. This can be in natural oiled oak, with a steel tray powder-coated ingranite, or alternatively entirely in black with an openpore paint finish for the oak frame. The steel frame is ideal for shoes left in the hallway, but has many other practical uses as well. The coat stand can of course be used equally well in a bedroom or guest room, and the console table for storage in an office. These craft highlights represent a style upgrade for any room.Versions: Frane and top panel: solid wood (natural oiled oak or oak with a black open-pore paint finish). Tray: powder-coated steel, in granite or black.

Theia

Theia - Floor lamp by Marset

Marset > Floor lamp

The Greek goddess Theia – mother of the sun, the moon and the dawn – lends her name to this lamp, whose design seeks to express the beauty of light and the fascination we feel for it. In Theia, the materials and shapes are merely the physical manifestations of the underlying concept: merging both light and shadow in a single piece.Theia has two faces: to discover them, simply swivel the fixture around its central axis. It can be pointed towards you for use as a reading lamp, or towards an object or a wall, creating a subtle, indirect light that immediately warms the atmosphere. Because Theia’s metal lampshade is totally opaque, this swivelling movement totally shifts the perception of the piece. Theia’s formal design is elementary and streamlined: two half-spheres, one placed horizontally and the other vertically, which intersect with each other. Just as in nature itself, these formal elements make it possible for the light from a source to be simultaneously projected, reflected, and absorbed by objects for our visual enjoyment.
