I ordered two of these.  They are lovely.  But, very hard.  However, as I use them, the seats are softening.  
I am not impressed with the shipping packaging at all.  It’s very flimsy.  I watched the FedEx guy drop one of these out of the back of his truck.  It damaged the ratcheting mechanism.  So, Wayfair had to send a replacement. 
I used these to accommodate guests over the holidays.   Had to supplement the bed cushioning with egg crate foam.  If you need a very firm sleeping surface this will work for you.
Overall, I am pleased with my purchase.   They are easy to set up.  They fold out nicely into a bed.  The sleeping surface is only a few inches off of the floor.  So, for us older folks it takes a minute to get out of bed.
