Solid Hardwood, Engineered and Laminate Flooring - Pianos and floating laminate floors

This forum is very informative, and a lot of my questions have been answered just by reading, but I've seen warnings against putting cabinets and bookshelves on floating floors. I have a piano in a room where I want to install floating laminate flooring. It's just a console, but it's old, so it is solid wood. I'm sure it weighs as much as a fully loaded bookcase. All the weight is carried by four metal casters.

Is this a bad thing? If so, what are the alternatives?

i don't think it will be a problem. seems i remember hearing that a pool table wouldn't be a problem - this is about the same thing.

you should be fine with placing the piano on the floating floor..i have done many...but you must not roll the piano an inch ...it could leave an imprint in the flloor..so when you move it ..lift it completely..also i would get some of them small protectors they use for kithen table legs..to put under the wheels once it is in place...good luck and enjoy the floor

It will be fine as long as you don't have something heavy, like loaded book cases, opposite of the piano, in the room.

What would happen then? To heavy for expansion?

Because two excessively heavy objects are opposite each other, they trap the floor and basically lock it in. Between the two heavy objects the floor swells or shrinks.

It either heaves/buckles or gaps and comes apart.

Sorry...but...

so logically that would apply with hardwood as well?

Yes, basically.

Engineered hardwood, is much more dimensionally stable then laminate core planks. It would be more forgiving then a laminate.
