Before clicking “add to cart,” there are a series of checks that separate a smart purchase from a piece of furniture that ends up shoved in a corner. This list is designed for affordable modern sofas, where the seller’s margin for error is paid for with thinner materials or longer delivery times.
1. Check the structure before the design
A cheap sofa that looks good often hides a frame made of particleboard or low-density fiberboard. Ask in the product listing or via chat: type of wood (beech, pine, board), thickness, and joining system. If they don’t specify, assume the worst. Curved seat slats in multi-layer wood hold up better than a flat, screwed-down board.
2. Foam density: the figure almost no one publishes
Look for densities of 30 kg/m³ or higher in the seat. Below 25 kg/m³, the seat flattens within months. In budget sofas, it’s common to find blends of foam and hollow fiber: comfortable at first, but they require fluffing the cushions every week.
3. Upholstery: read the composition, not the trade name
“Premium velvet” or “Belgian linen” are marketing labels. What matters is the composition: 100% polyester resists wear well but makes you sweat; blends with at least 20-30% cotton or linen breathe better. Fabrics with more than 25,000 Martindale cycles (the abrasion resistance standard) withstand daily family use.
4. Check the package weight and dimensions
A detail you only notice with experience: many online sofas arrive in two or three boxes via a courier service, not furniture transport. Check the maximum weight per package and whether the box fits in the elevator or stairwell. If the sofa is delivered assembled, measure the door and landing width beforehand. A 2.10 m sofa with fixed arms won’t fit in narrow elevators.
5. Disassembly and assembly: what they don’t tell you
Detachable sofas (screwed-on legs and arms) make access easier, but check that the hardware is metal and not plastic. A common mistake: buying a model with screwed-on arms without checking that the screws come with washers; with use, the particleboard splinters at the anchoring point.
6. Return policy and return cost
For large furniture, a return can cost between €40 and €120 depending on the courier. Check whether the seller covers the return by default or only for defective products, and whether they require the original packaging. Without this check, a sofa that doesn’t fit in the living room becomes an expensive problem.
7. Real lead times and stock
“Ships in 48 h” sometimes means leaving the warehouse, not delivery. Ask about the door-to-door lead time and whether the carrier gives notice with a scheduled appointment. In-stock sofas are usually models with standard upholstery; custom colors add 2-4 weeks.
8. Warranty: what it covers and what it doesn’t
The legal warranty in Spain is 3 years for new products, but wear from use (foam compression, fabric peeling) is usually excluded. Ask in writing what is considered a manufacturing defect.
9. Compare the price per seat, not the total
A 3-seater sofa at €399 works out to €133 per seat; a 2-seater at €349, to €174. This quick calculation reveals which deals are genuinely cheap and which only seem affordable.
10. Look for reviews with photos and dates
Reviews with real images of the assembled sofa and several months of age are the most reliable. Be wary of identical opinions published on the same day.
This list doesn’t guarantee a perfect sofa: in the budget segment, there are always compromises. Knowing which ones you accept is the difference between a smart purchase and a return.
