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-seater sofa, two armchairs, a coffee table, all seat and back cushions, and an assembly kit with fittings, key, and instructions. You don’t need to buy anything else.
At the moment, Siena is only available as a complete set. This allows us to ensure a consistent look and a more competitive price compared to selling the individual components.
Yes. The aluminium frame and Olefin fabric make it perfect for both outdoor and indoor settings. Many customers use it in enclosed verandas, basements or contemporary living rooms, as well as in British gardens and outdoor living spaces. Crafted in Italy, it combines refined design with long-lasting performance.
Siena pairs perfectly with the decorative cushions Marra and with the entire outdoor lighting range by Maanta. They are designed to create a cohesive ecosystem in your outdoor space, perfect for enhancing British gardens and terraces with a refined Made in Italy touch.
The overall footprint depends on the layout you choose. As a guide: the sofa measures 130×70 cm, each armchair 64×70 cm, and the coffee table 85×51 cm. A terrace of around 3×3 metres comfortably accommodates the full set, making it ideal for British gardens and outdoor living spaces.
Olefin is a synthetic fibre 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 furnishings, ideal for British gardens, terraces and outdoor living spaces.
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 aluminium won’t warp in the heat. In prolonged direct sunlight, the cushions may warm up: a pergola or a Maanta shade sail is the perfect solution. Crafted in Italy, it combines durability and refined design, making it ideal even for British gardens and outdoor living spaces.
The structure and fabric are designed to withstand rain. The open-cell padding allows water to drain through and dries quickly. For even longer durability, we recommend protecting the cushions during the winter months or in the event of prolonged heavy rain, especially in British gardens and outdoor living spaces. Crafted with Made in Italy quality and design.
The coffee table features a slatted aluminium top, allowing water to drain away and keeping it lightweight. The slats are closely spaced, so you can easily place glasses, plates and everyday items without any issues. Perfect for stylish and practical outdoor living in British gardens and terraces.
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—ideal for protecting surfaces in British gardens and outdoor living spaces.
We do our best to reproduce colours as accurately as possible. Slight variations may occur depending on your device screen.
Yes. The materials used (aluminium, Olefin) are specifically selected for both outdoor and indoor use. The manufacturer operates under ISO 9001:2015 certification to guarantee consistent quality—ideal for British gardens and outdoor living spaces.
About 30 minutes for one person, even without experience. The bush-and-insert system makes installation intuitive: each component fits into only one possible position.
No. Everything you need is included in the package: assembly spanner and complete fixings. No drills, screwdrivers or additional tools are required.
Yes, this is one of the main advantages of the bushing system. Unlike self-tapping screws, which can widen the holes over time, the bushings retain their grip even after dozens of assembly and disassembly cycles—ideal for maintaining reliable performance in British gardens and outdoor living spaces.
One person is enough. The aluminium components are lightweight and easy to handle. The bushing system doesn’t require force: you simply screw it in by hand using the supplied 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 cover, so your order arrives safely to your outdoor living space in British gardens and terraces.
You can clean the frame with a damp cloth. The cushions can be washed with water and mild soap. No specific products are needed. We recommend storing the cushions under cover during winter to extend their lifespan, especially in British gardens.
Siena is designed as a freestanding furnishing, not intended to be anchored. Once assembled, the overall weight of the set ensures stability even in moderate wind conditions. For particularly windy areas, we recommend placing it in sheltered spots, especially in exposed British gardens or terraces.
You can dismantle it and store it in its original boxes, or leave it assembled and cover it with a protective sheet. The aluminium structure is suitable for outdoor use even in winter; we recommend storing the cushions indoors during the coldest months. Designed and crafted in Italy, it brings quality and style to British gardens and outdoor living spaces.
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 straight away. We’ll handle the claim with the courier and send you a replacement component as quickly as possible, so you can get back to enjoying your outdoor space across British gardens and terraces.
