First, Check the Fabric and Sewing Quality
When buying a leather sofa, start by examining the surface material. Leather sofas are typically divided into full-grain and semi-leather options. A full-grain leather sofa is made entirely from high-quality cowhide, which comes from about 10 cows per set. It offers excellent breathability, environmental friendliness, and durability, making it popular in countries like the US and Europe. Semi-leather sofas use real leather on the parts that come into direct contact with the body, while other areas—like the back and bottom—are made from synthetic materials such as PU or PVC. This approach reduces costs without compromising comfort.
Leather types vary, including yellow cowhide and buffalo leather, and they can be classified by layer (top, second, or third) and origin (domestic or imported). High-quality imported leather, especially from Italy or Germany, is known for its superior softness, elasticity, color retention, and tear resistance. To ensure quality, always look for top-layer yellow cowhide, as it provides the best comfort and longevity.
When inspecting the leather, check for even texture, luster, and no visible scars or imperfections. Gently pinch a section of the leather; it should feel soft yet firm. After sitting, the leather should return to its original shape without noticeable wrinkles. A good leather sofa will feel smooth and supple under your touch.
Second, Inspect the Frame Construction
Test the frame by gently shaking the sofa back and forth. A solid frame should feel stable and not wobble. If possible, ask the salesperson to lift a corner of the base cover to check the internal structure. The wood used should be solid, free from pests, cracks, or knots. High-quality sofas use joints connected with dowels or mortise-and-tenon techniques rather than nails, ensuring long-term stability and durability.
Third, Examine the Fabric
If you're purchasing a fabric sofa, make sure the fabric is tightly woven and evenly attached to the inner padding. Pay attention to the armrests and the junction between the seat and backrest—these areas should be smooth and free of wrinkles. For curved armrests, check if the arc is smooth and well-formed. For patterned fabrics, ensure the design aligns correctly and the pattern is symmetrical without distortion.
Sit down and test the comfort level. The seat and backrest should support your body naturally, matching the curves of your back, waist, and legs. The height of the headrest and backrest should be appropriate, and the armrests should allow your arms to rest comfortably. When standing up, the fabric should not show deep or lasting wrinkles, especially around the seat and backrest.
Fourth, Evaluate the Foam Cushions
High-end sofas use high-density foam cushions with a density of at least 30 kg/m³ for the seat and 25 kg/m³ for the backrest. Some manufacturers add soft treatments to enhance comfort without reducing density, while others incorporate vertical springs for better resilience and longer lifespan. A good cushion should compress slightly when sat on and quickly rebound. Aim for a seat cushion thickness of about 10 cm after sitting down for optimal comfort.
Fifth, Assess the Internal Padding
High-quality sofas often feature a combination of nylon belts, snake springs, and high-density foam for the seat and backrest, providing excellent support and comfort. Mid-range models may use rubber fiberboard as a base, topped with medium-density foam and sprayed cotton, offering a firmer seating experience. Always check that the seat and back covers are constructed with a looper structure, and consider choosing a fabric with a weight of over 300 g/m² for durability.
For fabric sofas, look for tight weaves, no loose threads or exposed seams, and a firm tension. The stitching should be even and straight, with tight seams and rounded edges. High-quality imported fabrics often have enhanced features like anti-static, flame-resistant, and stain-proof treatments, making them more durable and visually consistent.
