Hi. Just wanted to share a couple of things we did to our 19 that others might find helpful.
To raise the mattress for ventilation, we used IKEA’s Luroy bed slats plus 3 or 4 bags of 1 in. wooden cubes and double sided tapes both bought from Dollar Tree and attached 2 cubes on each end of the slats to raise them up. It has so far held up well.
For the closet, we bought the following Jonaxel drawer organizer from IKEA, which fits almost perfectly (we have the optional drawer below the closet). To get it to sit flushed to one side of the closet, we had to use a half-inch strip of rubber we cut off from our bathroom floor mat. To prevent the drawers from sliding out during travel, we use a bungee cord across them.
We have so far been happy with these simple solutions.
