In photos, one sectional sofa looks as solid as the next, because the frame, the connectors between modules, the suspension webbing, and the motors are all hidden under the upholstery. Yet those parts determine whether long spans sag, whether a module fits through the door when you move, and how much floor space an open recliner takes up.
Factory drawings and material data sheets let you check these details before you buy. At Room Service 360°, a modern Italian furniture store in Philadelphia, the product pages for Gamma Arredamenti, Lago, and Nicoline Italia models include Product Specs sheets and exact upholstery data that spell out four of the five features below.
Solid Wood Frame: Gamma Arredamenti Tuxedo
The Italian factory Gamma Arredamenti builds its Tuxedo sectional on a solid wood frame. The product page states the frame material outright, and the drawing lists three set sizes, all 61″ deep and 30″ high: 102″, 120″, or 138″ across, with a chaise 35″, 41″, or 47″ wide.
Seat depth is 25″ in all three versions, and the chaise is ordered left or right to suit the room’s entrance. Upholstery is genuine leather or fabric, with stitching that matches the main color or runs a shade lighter or darker. The metal legs come in eight finishes, including chrome, brass, and titanium. If another model’s spec sheet doesn’t name the frame material, ask about it before you pay.
Modules with Detachable Connectors: Lago Air Soft
Air Soft, which Daniele Lago designed for the Italian factory Lago, has, per the manufacturer, an aluminum frame and patented hook-and-release brackets that let you separate the sections and rebuild the same parts into a different composition. The drawing of the 153¾″ × 66″ Air Soft 1902 shows the breakdown: two 43½″ seat modules, a 50¾″ × 58″ chaise, and two 8″ armrests.
The frame rests on legs of Extra-Clear or Smoked Grey tempered glass, or steel in Peltro and Titanio finishes, and the cushions contain a layer of certified goose down. Because the connectors come apart, the sofa splits into modules for carrying through doorways when you move or change the layout, then goes back together in the new spot.
Suspension and Cushion Fill: Gamma Arredamenti Newport
On the Newport sectional from Italy’s Gamma Arredamenti, reinforced elastic webbing on a hardwood frame works with a mixed fill: the polyurethane foam is covered with feather in the seats and with wadding in the backs. The result is a firm base with a soft top layer where you sit. Stitching can be ordered to match the upholstery or in a lighter or darker shade.
A pushdown mechanism with an air spring on the multi-density backrest cushions raises the sofa’s top edge from 32″ to 37″ for head support; for corner sections, the lift is ordered separately. Newport comes in two sizes, 106″ × 96″ and 120″ × 103″, with a 21″ seat depth, an 18″ seat height, and a left or right peninsula for an open floor plan.
Upholstery with Published Specs: Nicoline Italia Gary
For Gary, from the Italian maker Nicoline Italia, the configurator lists composition, Martindale abrasion cycles, and pilling resistance for the fabrics, and thickness, grain type, dyeing, and finish for the leathers. The figures vary within the collection: the blended Flair KOS fabric is rated at 18,000 cycles, the flame-resistant and water-repellent Flair YUC reaches 100,000 with a pilling resistance of 5, and the embossed top-grain Nobile leather is 2.0-2.2 mm thick.
Gary’s covers don’t come off, so there’s no sending them out for cleaning. For a family room with kids, choose the upholstery by its abrasion ratings and water repellency. The model comes 149½″ or 153½″ wide and 67¼″ deep, with the chaise on the left or right and stitching that matches or contrasts.
Recliner Mechanism: Nicoline Italia Wagner
Wagner, made in Italy by Nicoline Italia, has an electric recliner operated by a button on the inside of the armrest, with independent mechanisms that move the footrest and the headrest separately. One reclining seat comes standard, a second is available upon request, and the reclining sections ship as separate elements. The standard version plugs into a wall outlet, but for a sofa floating in the middle of the room, you order a rechargeable lithium battery for each reclining seat.
Per the tech sheet, Wagner is 65¼″ deep with the recliner open versus 43″ for the closed seat, stands 41″ high with the headrests up, and needs 4″ of clearance between the back and the wall. That’s why footrest space, the gap at the wall, and the power source go on the floor plan while you’re still choosing between the 97¾″ and 115¼″ widths.
What to Check on the Spec Sheet Before You Order
Before you buy, compare five parameters on the technical sheet:
- The wood species or metal in the frame, and the width increments
- Connectors between modules, in case you move
- Suspension webbing and the feather layer in the cushions
- Martindale cycles, pilling, or leather thickness when the covers aren’t removable
- How far the recliner extends, the 4″ wall clearance, and battery power
Room Service 360° designers can help you choose the exact size and chaise side for your floor plan, at the Philadelphia showroom or in an online consultation.
