Very comfortable chairs, they have a little bouce/rock to them like the vintage metal shell outdoor chairs. The chair  moves with you and this makes them very relaxing to sit in.  We find ourselves sitting at the dining table longer at mealtime and sitting in these chairs for a coffee, during the day probably because they are so comfy.  These chairs had the heaviest weight tolerance of all the sled leg chairs available,  so the construction would be the most sturdy.  Sitting in one writing this rewiew...happy with this purchase.
As other rewiews stated, the vinyl/pleather/ whatever the fabric is called does feel thin.  I did purchase a warranty, so any tears would be covered.  I felt it was worth the money given the chairs other good features.  Thin fabric was reason for 4 stars.  But 5 stars for WAYFAIR service!
