I purchased this queen sized sleeper couch for a guest room in my home. The fabric I chose was Capri Dove which is actually a true charcoal grey that I desired, not the pinkish hue that appears on the website. Strongly recommend obtaining swatches of any fabric that you might be interested in as some are quite different from the web images. The slip cover is very well made, lined on the skirt panels as previously mentioned. The mattress is 6 inches as described, thicker and more comfortable than any of the other sleep sofas at this price point that I looked at in retail stores. Customer Service (Brianne C.) was terrific. Inquiries I had were responded to promptly, and she assisted in helping to confirm that the swatch I had for my fabric was the accurate one so I could confidently place my order. This slip covered sleeper sofa is a great value.
