Thanks for your thoughtful review! We are happy to hear that overall, you are pleased with the order, but sorry to hear that the back height is not as perfect for you as we had hoped. All dimensions should be listed for each item on their respective product pages, and the great news is that if you happen to see a sofa/sectional that may be more suitable for your needs, we offer a 100 day return/exchange policy. Feel free to reach out to our support team for fee information and if you have any questions!
