"A 210mm lens will only shorten the working distance"

the OP said that he would be 4 m from the 3m wide object so a 450mm or above lens will not cover the shot
a 210mm will foreshorten the furniture but camera movements will be able to deal with the geometry of the furniture

for work I do a lot of location lifestyle room product photography on 35mm format and the 18,21,25mm focal lengths get used a lot
I seldom have the option of backing away far enough to use a long lens as we normally want as wide as possible
the OP did not say what depth the objects had or if the priority was everything had to be tacksharp
it is possible to shoot this at f22 on a 210mm and get a "pretty" shot nothing like Kens photo (not that Ken is not pretty)

My definition of pretty may differ from yours

Kens photo of the big nose effect is not really relevant to product photography as a full hight person at 4m on a 210mm would be about a third of the frame high not a full head close up
