  • Does Not Fit!
    Verified Purchase

    Was sent two identical "love seat" sections instead of 1-love seat + 1-2 seat EXTENSION for the couch. The love seat does not function as an extension it does not have a flat end to connect, the rounded tufting prevents the end from getting close enough for connection to occur.

Questions & Answers

  • Q:

    "Hi, I need help please. I purchased the 7 seat L and 2 of the two seat extensions. The extensions will not connect to any of the pieces in the L bc the front faceing tufted board has an extra piece of wood that sticks out and doesn't allow the metal connectors to reach eachother. PLEASE HELP! Also, the 2 seat extensions seem like they need at least one of those plastic legs that can with the 3 person seat. I have pictures of how the parts do not meet, please advise! I would hate to have the whole thing sent back!"

    • A:

      Please contact Customer Care under https://help.overstock.com/app/contact_page

    • A:

      I am having the same issue! Purchased the 2 seat extension but received 2 love seat sections (same item #'s) and the two rounded ends have too much tufting/padding for them to get close enough to connect. I am on hold with Overstock now hoping for some suggestions as I only ordered this combination because I needed a longer couch section for my room.
