Assembly that never lets you down
The bushing system that changes everything
Most garden sets are assembled with self-tapping screws that, season after season, widen the holes and loosen the joints.
Siena uses pre-installed metal bushings and inserts in the frame: slide in, tighten, lock.
The joints stay firm even after dozens of assemblies and disassemblies. The same principle used in the aeronautical industry, applied to a garden sofa. Thirty minutes, one person, no frustration.

Our strengths
Technology
Bushing joints
Pre-installed metal inserts in the aluminium frame. Slide in, tighten, lock: the joints stay secure even after years.
Materials
Powder-coated aluminium
Electrostatic coating resistant to corrosion: it does not rust and does not fade. A frame that is lightweight to move, rigid in use.
Fabric
High-resistance Olefin fabric
Synthetic fibre that repels water and stains, resists UV rays without fading, and dries in just a few minutes. Easy to clean with water and soap.
Smart
Optimised flat-pack
Each component is individually protected in a single compact parcel: it reduces shipping costs and arrives intact, with no unpleasant surprises.
Comfort
Open-cell padding
Drains rainwater and does not retain moisture: after a summer storm, half an hour and you can sit down again. Calibrated thickness to prevent sagging.
Ecosystem
Compatible with Marra and Cala
Integrates with Marra decorative cushions and the Maanta lighting range.
An outdoor ecosystem that grows piece by piece.
Why we chose Olefin
An aperitif, a sudden rain shower, a bright sunny afternoon: Olefin, the fabric of our cushions, is a 100% polypropylene fibre born to live outdoors. It does not absorb water, is mould-resistant, and withstands UV rays.
The cushion covers can be removed, washed, and put back in place. Because your space should be a pleasure, not a chore.

FAQ
FAQ
The complete set includes: a two-seat sofa, two armchairs, a coffee table, all seat and back cushions, plus the assembly kit with hardware, wrench, and instructions. You don’t need to buy anything else.
At the moment, Siena is available only as a complete set. This allows us to ensure visual consistency and offer a more competitive price compared to selling individual pieces.
Siena pairs perfectly with the decorative cushions Marra and with the entire outdoor lighting line by Maanta. They are designed to create a cohesive ecosystem in your outdoor space, bringing the elegance of Made in Italy design to American backyards.
Olefin is a synthetic fiber known for its excellent resistance to UV rays, water, and stains. It won’t fade in the sun, dries quickly, and is easy to clean. It’s the preferred choice for long-lasting outdoor furniture.
Yes. Aluminum is naturally corrosion-resistant, and the electrostatic powder coating adds an extra layer of protection. It won’t rust, peel, or require ongoing maintenance.
The cushions are designed to be cleaned directly on the surface using water and mild soap. The Olefin fabric is water-repellent and stain-resistant, reducing the need for frequent washing.
Yes. The Olefin fabric is designed for high sun exposure, and the aluminum won’t warp in the heat. With prolonged direct sunlight, the cushions may get warm: a pergola or a Maanta shade sail is the perfect solution for keeping your American backyard comfortable.
The structure and fabric are designed to withstand rain. The open-cell padding drains water and dries quickly. For even longer durability, we recommend protecting the cushions during the winter months or in case of prolonged heavy rain.
The coffee table features a slatted aluminum top, allowing water to drain through while keeping it lightweight. The slats are closely spaced so you can easily place glasses, plates, and other items without any issues—perfect for your outdoor spaces. Crafted with Made in Italy quality, it brings refined design and practicality to American patios and backyards.
The electrostatic powder coating is more scratch-resistant than traditional paint. Under normal use, it won’t scratch. For delicate flooring, we recommend applying felt pads under the feet.
We do our best to reproduce colors as accurately as possible. Minor variations may occur depending on your device screen.
Yes. The materials used (aluminum, Olefin) are specifically selected for both outdoor and indoor use. The manufacturer operates under ISO 9001:2015 certification to ensure consistent quality.
About 30 minutes for one person, even with no experience. The bushing and insert system makes assembly intuitive: each piece fits in only one possible position.
No. Everything you need is included in the package: assembly wrench and complete hardware set. You won’t need drills, power drivers, or any additional tools.
Yes, this is one of the main advantages of the bushing system. Unlike self-tapping screws, which can widen the holes over time, bushings keep a secure hold even after dozens of assembly and disassembly cycles.
One person is enough. The aluminum components are lightweight and easy to handle. The bushing system doesn’t require force: it tightens by hand using the included wrench.
On the contrary. Flat-pack packaging reduces the risk of damage because each component is individually protected inside the box. We ship with DHL Express, ensuring full tracking and insurance coverage—so your order arrives safely, ready for your outdoor space in American backyards and patios.
You can clean the structure with a damp cloth. Wash the cushions with water and mild soap. No specific products are needed. We recommend storing the cushions indoors during winter to extend their lifespan.
Siena is designed as freestanding Furniture, not anchored. Once assembled, the overall weight of the set keeps it stable even in moderate wind. For particularly windy areas, we recommend placing it in a sheltered spot.
You can disassemble it and store it in its original boxes, or leave it assembled and cover it with a protective cover. The aluminum frame can withstand outdoor winter conditions; we recommend storing the cushions indoors during the coldest months.
Siena is covered by a 2-year warranty from the date of purchase. The warranty covers manufacturing defects in the structure, fabric, and hardware.
Yes. The warranty covers manufacturing defects in the cushions, including issues with stitching and fabric. Normal wear and tear and accidental damage are not covered.
Take photos of the damage and the package at the time of delivery and contact us right away. We’ll handle the claim with the carrier and send you a replacement component as quickly as possible.
