Excellent CPAP cart! I was having a lot of trouble with yanking my cpap off the nightstand and every cpap cabinet I looked into was hundreds of dollars or made of moisture sensitive materials or didnt actually have any way to secure the machine. I put the cpap (resmed airsense) inside the top rack and it doesnt budge at all. Even if I did yank it, it would hit the side of the cart and stay put. I also like that any moisture will easily evaporate because of the mesh. Im still working out the perfect storage system, but Im probably going to take out the center tray and put a gallon of water and extra masksfilters in the bottom tray. A gallon will not fit in the bottom with both trays installed, but if you use liter size bottles, theyll fit on their side and you can use the other tray for masks and filters. Im also going to put a hook on the side to hold the mask when Im not using it, and maybe add some cable management underneath. LOVE IT.
