We purchased two grey and really like them.  The firm bottom is great... otherwise it would lose its shape.  The back cushions are a bit flimsy for my liking and will mis-shape soon if we are not dilligent with them.  The cylinder cushions make sofa very modern so we left them off.  They are also flimsy.  The color changes with the light-- seems lighter in the light and darker like the photo in the shadow.  Good purchase at a good price.
