I purchased two of these chairs to go in my living room.  They were very easy to assembly.  I simply screwed the feet on and slid the back cushions into place.  The chairs are comfortable and firm.  

In the picture, the seat cushion appears as though it's removable.  It is not.  It's sewn to look as though it is a separate piece, but in fact it is attached.  Additionally, I have the chairs positioned in my living space where the backs are visible.  Because the base is separate from the back cushion, there is a horizontal line on the back of the chair.  It is not a solid piece of fabric.  

Overall, I like the chairs and they were a great price.
