xCompact, featherweight knee pillow for side sleepers
Meet Circa Air's inflatable knee pillow—an ultra-light companion designed to slip into your travel bag or nightstand. When inflated, it becomes a soft, supportive curve that you can position between your knees or legs without bulk. At just 1.98 ounces and folding down to about 4x2 inches, it disappears in a tote or pocket, leaving room for the rest of your essentials.
Rather than a rigid foam product, this pillow offers adjustable firmness via a simple push-button valve and a few breaths. The result is a tailored feel that softens pressure points while you are lying on your side, helping you settle into a comfortable alignment as you drift off.
Ergonomic design without the bulk
The core idea is to support a natural line from hip through knee and ankle. The lightweight TPU fabric is gentle to the touch, with a smooth exterior that will not snag on sheets. By letting you set the level of inflation, you can fine-tune the cushion to your body contours and sleeping position.
- In between-the-knees use: Improves leg alignment and reduces lower-back strain by supporting the knee and hip stack.
- Adjustable firmness: Inflate more or less to match your sleep tempo and comfort preference.
- Quiet, quick setup: Push-button valve makes it effortless to reach your desired feel in minutes.
Travel-friendly and home-ready
Whether you are on a red-eye, staying in a hotel, or resting in a car seat, this knee pillow is designed to travel. It comes with a bonus travel pouch and fits easily into bags, purses, or even a coat pocket. Its compact size does not compromise on comfort when you need a little extra support after a long day.
- Travel pouch included for organized packing
- Versatile use at home or on the go
- Portable, lightweight design weighs under 2 ounces
Durable materials you can feel
The surface uses soft TPU fabric that feels gentle against skin and linens. The inflatable body holds its shape with a reliable valve system that is easy to operate, so you can re-pressurize after any layovers or naps. The product dimensions ensure enough loft without being cumbersome: roughly 9.8 x 7.9 x 6.3 inches when fully inflated.
Circa Air stands behind its knee pillow with customer-friendly policies and practical benefits. It is eligible for FSA/HSA, and returns are easy if it does not meet your expectations. This is a product designed to travel with you, supporting your chosen sleep routine without imposing a rigid claim about outcomes.
