3 years ago I bought a leather bed with Palan furniture. In the middle of the back of the bed there

This depends on what the material of the furniture is, how the craftsmanship is, and whether it is well preserved today.

The volatilization of formaldehyde gas is very slow, the cycle of activity is 1-10 years, and some can even be longer, but the initial year is the fastest and most volatilized, so people feel obvious, and the volatilization is slow after 5 years, and people are often easier to ignore. It is recommended to buy a formaldehyde detector (slightly expensive, can be used for a long time) or a formaldehyde detection box (one-time use, affordable, judged by the change of chemical reaction, and the detection is more accurate) to detect the current formaldehyde content and make some formaldehyde treatment measures in time.

You can move in about 20 days, because you have been decorating for 3 years, formaldehyde is basically very little, as for the new furniture you buy, how much formaldehyde is contained, 20 days of time to open the window for ventilation, buy some plants: pothos, drug weed, etc., but also put potted water in the house, formaldehyde is water-soluble, so, after 20 days, there is basically no problem!!

Swift ants can write about the origin or history of furniture, generally with a period of time, and can write from its source, the story it carries, and the historical feelings.

Yes, now in these years, if people want to open it, it is useless to prevent any security door.
