Arched Brass Arm · Marble Base · Over-Sofa Floor Lamp · Mid-Century Modern
An arc floor lamp in the Italian Mid-Century Modern tradition — a slim brass arched arm rises 71 inches from a solid white-and-grey violet-veined marble cube base, sweeping over to deliver a brass dome shade above seating or table at the far end of its arc.
Designed for over-sofa lighting where ceiling-hung pendants are not practical — the arched arm reaches across a sofa, daybed, or reading chair to suspend warm directional light overhead from a stable floor base.
Why It Stands Out
Solid Marble Cube Base
White-and-grey marble with violet veining in the Italian-tradition palette — heavy enough to anchor the full arc.
Arched Brass Arm
Slim arched brass arm reaches forward from the base — over-sofa lighting without ceiling-hung fixtures.
Brass Dome Shade
Half-dome brass shade directs warm light downward over a sofa, daybed, or reading chair.
Finish Options
White Marble & Mirror Polished Brass
White-and-grey violet-veined marble base with warm gold-brass arc and dome — Italian Mid-Century palette for traditional and Hollywood Regency interiors.
Black
Matte black arc and dome — graphic architectural silhouette for contemporary and modernist interiors.
Plug Region — Choose at Checkout
Natural marble variations. White-and-grey violet-veined marble bases vary block to block — your piece will share the overall palette but the exact veining pattern will be unique. This is the inherent character of natural stone.

Setup & Care
- Plug-in floor lamp — no electrician required. Plug the 59" cord into any standard wall outlet for your selected region.
- Two-person handling for placement. Solid marble base is heavy — lift from the base, never the arm.
- Place on a level, hard floor. Avoid soft rugs that can shift under the marble weight.
- Bulbs not included. Use a warm-white 2700–3000K LED bulb with standard E26/E27 base.
- Wipe marble clean with pH-neutral stone cleaner. Avoid acidic cleaners (vinegar, citrus) — they etch marble.

Frequently Asked Questions
Will the arc reach over my sofa? +
The arc spans 45.3″ / 115 cm horizontally from the base, with the dome shade hanging at roughly 60–66″ height — designed to reach over a standard 32–38″ deep sofa with the base placed alongside. Confirm clearance for the marble base footprint when planning placement.
Will the marble base look like the photo? +
No two marble blocks are identical — your base will share the overall white-and-grey palette with violet veining, but the exact pattern, vein direction, and tone will be unique. This is the inherent character of natural stone.
Which plug option do I select? +
Choose your country's standard outlet at checkout — US (110V Type A/B), UK (220V Type G), EU (220V Type C/F), or AU (220V Type I). The lamp ships factory-wired for your chosen region.
Is it dimmable? +
Yes — TRIAC-compatible when fitted with a dimmable E26 / E27 bulb on a standard wall dimmer.
Is it suitable for hospitality and trade projects? +
Yes — well-suited to luxury hotel suite living rooms, members'-club lounges, restaurant lounge corners, and high-end residential over-sofa applications. Trade pricing and specification packets available.

The stone story
One block. One lamp. One veining.
Marble is quarried in blocks, cut into slabs and hollowed thin enough for light to pass through — when the lamp is on, the veins show like ink in water. Because no two blocks are alike, every piece is one of one; the veining in the photos is a guide, not a promise. Prefer travertine, alabaster or a coloured marble? We cut those too.
Choosing a table or floor lamp
A lamp is sized to the surface and the seat next to it, not to the room.
