We ordered the sapphire (blue) chair.  The color looked a little darker, like a washed navy, maybe, in the picture.  But this is definitely royal blue.  I also thought that the fabric used for the outer covering would be more "pliable" than it is.  It makes me think of fabric used for tents.  The ad says, "...the cover is made of smartmax fabric."  I just didn't know what that meant.  So, hopefully this will help someone else when making a decision whether you want this or not.

I do think that this fabric will be durable.  The kids sit or lie on this at times, but their favorite thing to use it for is to run and jump onto it (on their bellies) and slide across the wood floor of the living room.  ...I'm kind of thinking of giving it a try myself.

I hope that this info helps someone.
