Heavy Furniture on Wood Floors

Q: While cabinets along a wall are attached via screws, therefore displacing weight to the wall, bedroom/office furniture such as armoires, full dressers and desks w/computer hutches may actually load much more weight onto a floor. What do you suggest in cases like this?
A: The easiest suggestion here is simple: avoid floating floors. Although the attachment to a wall does displace some weight, the largest problem is a large area of weight on the edge of a floor, similar to ceiling to floor book cases. I have seen many rather heavy objects, pool tables being the popular choice, succeed over floating floors with the proper underlayment. Keep in mind these are usually over 6mm cork underlayment and are in the center of a room, not at an edge.
Your best bet to avoid this kind of issue is to use a floor which nailed or glued down. In the case of glue, give the floor plenty of time to cure before placing weight on it. Also, think about using items like area rugs as a buffer between your furniture and floor to prevent scratching and denting.
Floors like Brazilian Walnut and Santos Mahogany are perfect for ideas like this as their natural hardness ratings make the more resilient to denting. Also, well built engineered floors using harder species, usually exotics are your best bet here and they look great too!
