I had these for one month and the middle support bar already broke. The middle support moves out of place w the slightest movement. The entire frame as a whole also moves so easily across the floor if u have non-carpeted floors (I have tiled wood) so you need the friction tabs for under the corners of the bed as a must if you don’t want your bad moving away from the wall every time you climb into it or sit up in it. It works decently without the middle support but I expected to get more than one month use out of it.
