United Express (SkyWest) has new seats on their CRJ-700 aircraft and they look great, but are terribly uncomfortable. The seat design is visually outstanding and provides a new and modern feel to an otherwise dreary and cramped cabin. Unfortunately I was able to experience the seats for a 3.5 hour flight from ATL to DEN and they became incredibly hard very quickly. Regional jets like the CRJ series are best for short flights (less than two hours) because their cramped cabin and lack of in flight amenities. The new seats wouldn't be bad on a short flight, but are unbearable for four hours. United needs to keep their focus on customer experience rather than unending cost cutting.
