Have you ever tried to learn on the bed? It’s pretty hard, isn’t it? That’s because the bed and the pillow aren’t designed for reading. To do reading on the bed with comfort you will need to use a bed rest pillow. This keeps your alignment proper all the time.
The function of this type of pillow is to keep your back straight when you’re reading. This ensures that you won’t get tired easily. Another useful feature is the armrest. This simulates the feeling of sitting on a chair and reading on a desk. Read also: Finding the fish.
So the point is, they keep you comfortable and supported at the same time. This also means that you won’t slide down your pillow as you’re reading. For me, that’s a massive irritant when reading on the bed using a normal pillow.
