If you plan to purchase items at a discount, or take free items at giveaways to help furnish your new home, you may want to be cautious. There could be major unseen issues present in these items.
It is very important for you to never take and reuse any mattresses offered at a tag sale or being given away. While not guaranteed, there is a risk of bedbugs for these items that is higher than other items. Bedbugs can severely complicate life in your new home.
Home furniture can also have bedbugs, as well as many other pests, which could lead to several issues in your home. Additionally, when finding these items, you may not know how long these have been outside. Even if the furniture looks to be in perfect condition, you could have items that have mold issues, or other undesirable qualities. Any item you plan to purchase that has a possibly moldy smell, or has obvious damage from mold, should be avoided.
If you find coffee tables or dining room tables that look like they may work for your home, it is necessary to check these items thoroughly. Items that are made of wood can hold up well, and these aren't as easily damaged by most bugs and mold. However, if you do decide to bring these to the new home, you must clean them with a solution that will not damage them, while still getting it clean enough to enter the home.
Inspecting all items that you receive second-hand will improve the chances that these are clean and safe for you and your family. However, if you have doubts it may be a much better idea to purchase items from reputable dealers.
