MATERIAL GRADE
This variable evaluates the nobility of the materials, ensuring that the product is crafted with high-level raw components.
Upholstery: 100% long-staple natural linen
The upholstery of the Verona Sofa is made from 100% long-staple linen, a natural fiber of great purity and uniformity that provides freshness, breathability, and historically recognized nobility. Its fully pure composition, free from blends, ensures homogeneity and consistency across the fabric. Sourced from European crops, linen is a less common raw material than cotton, though not as exclusive as fibers such as silk or vicuña.
Wood: European Walnut + European Oak
The structure of the Verona Sofa combines two woods with a long tradition in high-end furniture: European walnut and oak. Both are distinguished by their density, resistance, and historical recognition as noble woods. Only solid Class A wood is used, carefully selected to guarantee purity and absence of visible defects.
In terms of market value, European walnut has consolidated its position as one of the most appreciated and expensive woods, while oak maintains a stable and high valuation.

Global Score: 70,4 / 100
The Verona Sofa combines premium materials—natural linen upholstery with a noble European wood structure—achieving a solid result consistent with Quality Sphere standards.
DURABILITY
This variable evaluates the product’s resistance to use and the passage of time, considering wear, abrasion, fatigue, cleaning, environmental exposure, and aging.
The Verona Sofa is designed to maintain its integrity and comfort over time. Tests on fabric, structure, and cushioning demonstrated performance well above average: the upholstery withstands intensive use without premature deterioration, the cushions preserve their resilience after repeated impacts, and the solid wood frame maintains stability without significant deformations.
It also shows excellent performance against common stains and indoor light exposure—key factors in real domestic use.
Quality Sphere applies internationally recognized evaluation protocols, but raises the requirements to align them with its own standards of excellence. In this way, certified products not only pass technical tests but also reach the high levels of quality demanded by Quality Sphere to ensure their distinction

This variable evaluates the consumer’s perceptual experience when interacting with the product, analyzing how the material conveys its essence through touch and the impression it creates on the user. It focuses on the immediate sensation produced by direct contact, considering both the physical response of the material and the emotional interpretation received by the individual.
The direct touch of the 100% linen upholstery was rated as soft and natural, free from roughness. The HR foam and goose down cushioning showed excellent resilience: it adapts comfortably and quickly recovers its shape, ensuring premium comfort. The seat and backrest presented a uniform distribution, free from lumps or gaps, reinforcing ergonomics and immediate comfort.
Another distinctive aspect was the perceived nobility: participants immediately recognized the authenticity of the materials, highlighting linen and wood as natural, high-quality elements. The test also confirmed structural silence, with no creaks or mechanical noises during use—a clear sign of build quality.
As a nuance, some users perceived the linen as slightly cooler than ideal on first contact, although this characteristic was interpreted positively as an indicator of natural breathability.
“The upholstery integrates seamlessly with the wooden structure, resulting in a product with finishes that border on excellence.”
“The freshness of the linen feels like a mark of quality, especially for use in warm climates.”

CRAFTSMANSHIP
This variable evaluates the precision of the product’s finish, ensuring uniform results free from imperfections and consistent with superior quality standards.
The inspection of the Verona Sofa’s finishes reveals a level of execution characteristic of the high-end segment. Every detail, both visible and hidden, was assessed under a thorough protocol that included reviewing symmetry, leg alignment, fabric uniformity, seam regularity, and the quality of joints between fabric and wood.
The results confirm precise craftsmanship: seams remain consistent and balanced, corners are clean and symmetrical, and material joints are carefully executed, free from gaps or visible excess. The upholstery is evenly tensioned, wrinkle-free, and the legs display a homogeneous, elegant finish.
Even in hidden areas such as the base, staples and webbing are arranged with strict order, reflecting execution coherence beyond what is visible at first glance. Cushion profiles remained uniform after initial use, and no residual odors from adhesives or varnishes were detected—reinforcing the impression of a carefully crafted, clean product.
Global Score: 90 / 100
The Verona Sofa achieves an outstanding level in this variable, where the precision of visible finishes and attention to hidden details confirm construction quality consistent with premium-range standards.
