If you're shopping at Dania, it's because you've realized that IKEA doesn't exactly cut it anymore but you still can't afford to spend $10,000 on a couch. The quality of their furniture seems pretty high. You won't find a lot of particle board here. I've purchased a dining table, two sofas, an armchair, and an ottoman from them and all items are still sturdy and look great. I'd say they beat places like Pottery Barn and Crate & Barrel in terms of prices and value. However, Dania mostly carries contemporary styles that are best described as "Scandanavian" in design. It always seemed to me that their selection of more traditional furniture is smaller, but maybe that's because I've never sought that out.
The salespeople are always very helpful (patient and not at all pushy), though they get pretty busy on weekends. They're very willing to go through the many binders and books at the counter as well as call around to find out your options for a particular piece. Since this store location is kind of small, if you don't see exactly what you want out on the floor, I'd recommend you ask what else is offered in the same line. You might also go to check out their store down in Southcenter since its showroom is a lot bigger.
The delivery service was great. Because they had the furniture in stock, I got a couch, armchair, and ottoman delivered just days after buying them. The delivery guys were on-time, friendly, and fast.
