A bean bag molds to your body, which is exactly why the wrong cushion, or no cushion, can leave your neck or lower back unsupported over a long reading or movie session. The fix isn't a random throw pillow. It's picking the right shape for what you're actually using the chair for.
For reading and neck support
The Inga Reading Cushion is shaped specifically for this: a smaller, firmer profile sized to support your neck or lower back while you're sitting upright with a book, rather than a general throw pillow that just adds bulk.
For lower back and lumbar support
The Shara Long Cushion is built as a lumbar shape, which is the piece to add if you're using your bean bag as a real seating spot for longer stretches, not just an occasional perch.
For general styling and comfort
The Inga Cushion and Shara Square Cushion are standard square throw pillows in the same OEKO-TEX-certified corduroy as the bean bags and sitting balls they're designed to sit next to, so they read as a set instead of a mismatched add-on.
How to actually pick
Match the cushion to the use, not just the colour: reading cushion for upright support, lumbar cushion for longer lounging, square cushions for everything else.
