First of all, we will separate cabinet furniture and upholstered furniture, since their quality parameters differ in many respects.
It is clear that no matter how high-quality it is, but if the furniture is scary at first glance, then it is unlikely that possession and use of it will give you pleasure. It is on this basis that the initial selection is made, literally at the level of feelings, “like - dislike”, but then feelings should give way to a cold and prudent calculator.
Do not even consider buying if they refuse to show you a furniture quality certificate - this is the main document for study, everything else later. It indicates not only the usual class of furniture in this case and state standards that guided the manufacturer, but also the content of harmful substances in the materials. Yes, yes, they are always there, because for gluing, pressing, coloring, varnishing, drying, and other things, special compounds are used that contain formaldehydes, phenols and other harmful, but not entirely clear components for us. But we will definitely be able to determine for ourselves the possibility of buying this or that furniture, having found in the certificate an indication of its class in terms of formaldehyde content, as the main harmful component. These are class E1 (up to 10 mg per 100 g of dry wood), class E2 (10-20 mg) and class E3 (30-60 mg). Less is better, and children's furniture is generally allowed only in class E1, without options.
Now that we have weeded out the “harmful” furniture, we will select good quality furniture for its integrity and build quality, for which our attentiveness and patience will come in handy. Look into each box, take a closer look at all surfaces - there should be no chips, scratches, enlarged gaps in the doors and loose parts. If the assessment of the quality of furniture in laboratories is done with the help of vibrating tables, chemicals and presses, then you will have to rely on yourself and your own attention, and you cannot go wrong in this matter. Let the store manager shift impatiently from one foot to the other and rush you in every possible way - show firmness of character, because the claim for the quality of the furniture will subsequently not be addressed to the manager, but will fall entirely on your shoulders.
Pay attention to the condition of the hardware. Door hinges, locks, fasteners, etc. – they will also give you an idea of what you are going to buy. There are also indirect indicators by which the quality of furniture is determined - these are the characteristics of the packaging (good furniture is unlikely to be transported in ugly packaging, and vice versa - no one will spend money on packing low-quality furniture into something expensive that does not correspond to its class), conditions warranties, information materials, and assembly/dismantling instructions for the product.
Well, if after such a careful selection there will be at least a couple of products, one of which you will give preference to for its functionality. But it’s better not to buy anything this time than to buy something of poor quality or unhealthy.
It would seem that here it would be possible to do without abstruseness and simply choose what you like. But take your time, upholstered furniture has its own parameters, which we will now show.
First of all, we examine the product passport and see how “natural” or “synthetic” it is. The parameter is important, since the more synthetic materials, the more toxic the furniture will be in the event of a fire or even a slight burnout. The fact is that the foam rubber used more often than other materials is capable of releasing hydrogen cyanide and other dangerous substances during combustion. The second characteristic associated with synthetic materials is their electrostatic properties. If natural components practically do not accumulate static, then synthetics attract dust by accumulating it.
The quality of upholstered furniture is also determined by the quality of fittings, which, although for the most part hidden, are still visible in some places.
Every time you go to the store to buy furniture, be patient and set yourself up - in no case compromise with yourself and do not buy products of lower quality than you would like initially.
