Excellent construction. These are nice and well-cushioned and seem sturdy, although we just got them so I don't know how they'll hold up. If they fall apart I'll update. The dimensions are accurate and they make our outdoor chairs more comfortable than they have been in years. Only four stars because the red color is rather more muted in person; the pictures show a more vibrant, intense red, and the actual cushions are a dustier color. Since returning them would be a hassle, we'll live with the dull red, but it's slightly disappointing.
