The gray color is very nice. Seems sturdy enough for two young children to sleep on. The trundle part doesn't really have anything to hold the mattress in place except for the front panel. It's sturdy enough but definitely not something to move around a lot if you like to rearrange your room layout. And definitely not a bed to be rough with or jump on if you have little ones that like to climb and jump.  Stylish when not in use as a bed.
