I found this definition... it's a little "horoscopy" for me, but it seems to fall in line with Lynn's post: A classic, enduring design, transitional style is a union of traditional and contemporary furniture, finishes, materials and fabrics. To call to mind a fresh, tranquil mood, the transitional palette relies on a lack of color. A simple approach is taken with carefully chosen accessories. The look balances both masculine and feminine qualities for a comfortably contemporary design. A transitional look to your home generates an easy, welcoming atmosphere and mixes it with the sense of the traditional that shows off your good taste. Elegant and relaxed, trendy and tasteful, transitional style blends the best of traditional and contemporary looks. Transitional furniture is about bringing together comfort and minimalism with the attractive styling of traditional furniture. The lines are simpler than those found in more traditional styles, but are not as simple as contemporary. There are two sub-styles: * Casual. This style has elements of classic style, yet is cozy without being overly hip. * Eclectic. The general look of an eclectically styled room is integrated by prudent use of color and finish, shape and texture. Transitional family room furnishings combine both contemporary and traditional furniture styles. It effortlessly adjusts and combines with an assortment of styles, joining clean lines with fancy curves, and natural wood finishes with smooth, brushed metals. Fabric choices range from geometric and graphic patterns to classic textured solids. To get the look of transitional décor mix and match a variety of contemporary and traditional pieces. "Transitional" is also used to describe blended interior architecture, for floor plans that bring together formal spaces and fine points of traditional architecture with open, multitasking ones. An additional burst of color here, an unexpectedly detailed bit of decoration there  transitional is a style that can communicate accents of the eclectic and the unanticipated. You are on the avant-garde of design if you take pleasure in the transitional style. People who enjoy this style are taken with smooth and contemporary furniture and a minimum of accessories. They would select a lamp, a picture or a vase only if it makes a statement, and they have good judgment when it comes to line, scale, and drama. Do you prefer plain, clean lines and geometric shapes? Are you inclined toward light woods, like natural maple when selecting furniture? When you add ornaments to a room, would you most likely pick new accessories that are positioned sparingly and carefully all through the room? If you answered, "yes" to these questions, then transitional style is for you. Here is a link that might be useful: quote source

You have a lot of straight, contemporary lines so I would keep going with that, but I'd use a couch with a few distinctly different details so you don't get that "tried to match but missed" look. For instance, continue the squared arm, but look for a lower arm that isn't full-depth like the loveseat - for instance, Pottery Barn's Seabury (actually I like the dark wood frame and flared legs on that one, which would tie back over to the bookcases) - or a box-style arm/back like Crate & Barrel's Presley which also has that nifty wood frame. Mitchell Gold's Fred couch would be a really awesome transition between the Eames chair and the existing loveseat, with the square shape and tufted back, if you could find some way to keep the Eames chair in the room. Make sure the scale of the two pieces is the same, paying special attention to the seat height - it looks kind of weird to have one seat significantly higher or lower than the other. I think a low-to-the-ground (very short legs, not low seat) style would work better than a skirt if you want a less "leggy" look. Ikea's Karlstad doesn't look bad though, and would be an option if your budget is so tight it squeaks. ;-) The long cover seems to only come in white but you might find a great fabric cheap on Fabricguru.com or eBay and have a replacement cover sewn up using the white one as a pattern. You're not confined to a print unless you want one, but if you do want to go that way I'd look for something in a Deco or Mid-Century Modern style, either very subtle or strongly graphical; but I think a compatible solid in a heavy brushed canvas or twill would be just fine, especially with pillows that bridge the colors. Leather is also an option to consider, if it's in the budget. (If you were keeping the black Eames chair in the room, this black/beige print would be too cool.) BTW, if I may make an unsolicited comment, the pillows on the loveseat are a little traditional in style for the rest of the room, which skews contemporary. A more modern pattern like C&B's Spotlight or Kramer (outrageously expensive, but places like Target are knocking off things from spendier stores like C&B and Pottery Barn) would suit better, IMO. If you sew or can have pillows sewn, this contemporary tapestry fabric would work wonderfully with your colors. But, you didn't ask that so feel free to tell me to stuff it if you're in love with your pillows. :-) (Pun not intended.) Your other option is to call the manufacturer of your loveseat to find out if they still make that model and fabric, and go matching. There really is nothing wrong with that.

Houzzers! I think I've convinced my hubby to sell the media console as I believe I can get about what I paid for it (he's all about the almighty dollar). Can you recommend a better TV console design that might work in it's place??

Yes, more like this blue? https://www.potterybarn.com/products/lyndon-upholstered-armchair/?catalogId=41&sku=1592244&cm_ven=PLA&cm_cat=Google&cm_pla=Furniture%20%3E%20Chairs%20%3E%20Fabric&cm_ite=1592244&gclid=EAIaIQobChMIz5OfsrKU4gIVHrbACh3WggRUEAQYBCABEgIf3PD_BwE What about lightening up your coffee table, too? Side tables..I like this one but there are literally hundreds of side tables to choose from...it depends on your personal taste...
