A lot of brides say they want a seamless dance floor thinking these floors will not have horizontal and vertical lines running throughout. They think that it's a whole piece. Well, I hate to be the one to tell you, but it's not a one-piece wonder. In fact, it's impossible to bring in an 18'x18' dance floor through the reception doors without breaking it apart. Think about it. So why does the event industry call it "seamless" dance floors? Technically they are not "seamless" because they need to be in pieces for easier delivery. The term "seamless" is in reference to the seams surrounding each 3'x4' or 4'x4' square.
Some dance floors have metal seams surrounding each square. Some dance floors don't show metal seams. The dance floors with metal seams are NOT "seamless" because you can see the black/gray metal lines throughout the dance floor (see Example A). The dance floors without the metal seams showing are considered "seamless" because they appear just that (see Example B). TIP: Before signing a contract with an event rental company for a "seamless" dance floor (especially a WHITE "seamless" dance floor), ask the sales rep if you can take a look at a sample. It's always a good thing to see what you're paying for before dropping $800-$2500 on a dance floor.
Example 'A' above: White dance floor with metal seams (considered non-seamless)
Example 'B' above: White dance floor without metal seams showing (considered seamless)
