Both my boys need new beds. I am wondering how big the kids Ikea beds are (are they the standard twin size or more like toddler sized)? And how usefull is it to get one that expands? Also I would like to know about the Ikea mattresses and how comfortable they are. I will try them out in the store before buying but I just thought I would ask first. I am also wondering how well they will hold up. All my Ikea furniture has held up realy well for us and I am hoping the beds will hold up well too.

thanks,

Jessica.
