Would you like to sit in your car, chair, boat, airplane, or anywhere else and be pain-free—no matter how long you’re sitting? The SoftSeat® Portable Seat Cushion shifts your hips, pelvis and back into the proper, pain-free position. Helps minimize lower back pain from prolonged sitting. Eliminates pain from “hot spots.” Can raise or move you forward. Zippered and interchangeable parts. 100% satisfaction guaranteed.

They design their seat cushions so your hips and pelvis are shifted into the proper, pain-free sitting posture. After many years of listening to customer feedback and experiencing the SoftSeat® Portable Seat Cushions ourselves, they recommend you use a SoftSeat® Cushion Base with the SoftSeat® Lumbar Support for best results.

That’s why they created the SoftSeat® Portable Seat Cushion Base/Lumbar Combo as a Best Value option for customers.

They offer two anchor options.

  • Non-Skid Strips (most popular option)
    More portable option — use carry handle and move easily to different seats. Two 1" wide x 10" long strips of black webbing with black non-skid rubber are hand sewn to the bottom of the cushion (see the upper left image).
  • Straps
    Best option if using Cushion Base for one purpose, such as in an aircraft. One-inch straps with adjustable buckle are hand sewn from side-to-side. Two hook and loop fasteners are hand sewn to the back (see upper right image).
