We've actually been using it for almost 2 months; I wanted to wait until we'd lived with it before I gave you guys my official opinion.
The verdict - I LOVE IT!
The chair, with accessories, only cost us $30 - much less than traditional, bulky high chairs. The tray can go right into the dishwasher and the seat is smooth molded plastic - no crevices for hiding crumbs! If we have a messy feeding all it takes is a wet rag to get things cleaned up. The frame is lightweight and easy to move yet surprisingly stable.
The designer in me loves the clean lines and adult-friendly color palette - no cartoon characters here. Overall I would give it two thumbs up and my mommy seal of approval!
