These are perfect for the play room and are a high-quality foam.  They are very comfortable and I am also hoping to use them as an alternative sleeping place for those few nights a year we have guests.  The kids also love opening the chairs and standing them up on the side to make a fort.  I am very pleased with my purchase.  I had originally gotten the orange ones, but the shipping was delayed.  Wayfair did a great job communicating and giving me options and ultimately I think the lime green chairs work better in our space.

Update:  We put queen sheets on these and the kids bunked on them when we had family in town for the holidays.  This is such a great extra bed that doesn't have to look like one the other 360 days a year.
