Although rare, plastic cabinets are susceptible to cracking, splitting, and snapping, which are their biggest safety issues. If the cabinets come with synthetic wicker, broken woven strands can result in sharp edges. This means plastic cabinets must be taken care of properly. Their installation, if possible, should be done by professionals. Also, opt for formaldehyde-free cabinets to ensure there are no toxic gases released within your home from your furniture.
