they're both exactly the same except one is round & one is square. personally, i would choose which ever one was more comfortable. if they're both the same in comfort, i would choose the round/circle shaped one - it's more attractive (to me) than the other.

Memory Foam Oversized Chair seems to be the best chair for ultimate comfort.

'Lumi Source Solid Mitt chair' is looks better to me.I think others also chose it.

Not the color, like which chair looks better? I tried them both in stores, and I still can't decide!
