How does the furniture aspect work? Do they give to you pre-built like the displays or do you have to put it together at home?

the pice i bought came in a box ,i had to put it together, it depends on how you want it in a box or assembled i got it in a box (new) assembled or display (scratches or blemishes) .up to you

Couches and recliners come assembled. Chairs and tables need to be assembled unless floor sample

Depends on what it is. Usually they require some assembly .

You have to put together at home

Not sure but you can try and see if you can buy the floor model

Most of the time...You have to Assemble the Pieces yourself....some do come assembled...or You can pay them to Assemble for You👍
