Hi RTR,
I haven’t seen any reviews about the Glideaway Space Saver frame but the reason I like it is that it has smaller gaps between the wires and a more evenly supportive surface than some of the other similar platform bedframes. There is more about the wire grid platform bedframes in post #10 here.
Most of these types of platform bedframes are strong and don’t have any durability issues but all them also seem to have a few that have developed squeaks over time (which should be “fixable” if you find the source of the squeaks) or a few instances where a weld or the frame has broken but these don’t seem to be the “norm”.
