I use my Nexus 7 tablet constantly, often at my desk, and often while on a couch or in bed. (That last is bad. Don’t judge me.) It’s hard on my hands; I needed a way to support the device.
At a computer store, I saw a tiny pyramid meant for phones, which I’ve shamelessly copied here, in enormous format.
I started with a buckwheat pillow purchased at H Mart, an Asian goods store in Philadelphia. The pillow was a tube, with a zip-off cover, which I removed. The insert was actually rectangular, which suited my purposes nicely. Here’s a similar one to the one I bought, though mine was more rectangular:
I shook the buckwheat kernels down to one end of the liner, and chopped off the excess fabric. The trick to making the supportive pyramid shape is to sew that open end in the opposite direction to the other end.
See the seam lying along the table, below? The opposite seam should go from the table to the ceiling — perpendicular. Test your pillow with your device before sewing the seam, though, to make sure you’re happy with the stiffness and support.
Then I pinned out a ledge at the bottom edge, so that the device had a base to rest upon. Stuffing it as full of buckwheat hulls as I could, I ran one row of pins right up against the buckwheat, then ran a second row a distance away, to keep the rest of the hulls from shifting beneath my sewing machine’s needle.
(Don’t do this. Instead, baste. It’s the only thing that will actually keep the hulls from shifting.)
Using a zipper foot (to get as close to the hulls as I could) I then stitched along the first row of pins. Then I stitched again, for security, about a quarter inch away.
That took care of the inner filling.
Then I took a lightweight upholstery remnant, and made an over-sleeve. (You should iron yours; I was lazy and took the picture first.) This is done exactly the same way, but without sewing the ledge along one end.
I put a zipper along the second, perpendicular, seam (the one that goes upright). I wanted to be able to change the cover out if I felt like it. (You’ll want to make the zipper nearly as long as that seam; otherwise it will be very difficult to get a stiff pillow into the slipcover.)
Here’s how the finished support looks from the side.
Theoretically, you could stuff it with fiberfill, but I found that the weight and distribution of the buckwheat hulls is much more effective, and also allows the support to adapt more easily to other devices.
It’s sturdy and stable enough that I can use the device without having to add additional support — which is far more ergonomic and comfortable than holding it in one hand while navigating with the other.
It stores my glasses nicely, too; I’ve begun to think of it as my little gnome. And wouldn’t this make a fine book support for someone who reads in bed? You know, as I should be doing, instead of staring at the blue screen just before sleep?
