Tsumbay Memory Foam Seat Cushion - XL Size (18.5”x16.5”), Firm Support Coccyx Cushion for Office Chair, Tailbone Pain Relief with Removable Washable Cover & Handle for Car, Wheelchair — Open-Box, 44% Off

【XL Size for Greater Coverage】A solution designed for larger seats. With increased dimensions of 18.5” x 16.5” x 3.14”, it provides a more expansive seating surface for office chairs, car seats (especially trucks/SUVs), and wheelchairs, effectively addressing the "too small" issue and ensuring full support for the tailbone area.

【Secure Non-Slip Base & Contouring Support】Features a non-slip PU leather bottom to stay firmly in place on smooth chair surfaces. The high-density memory foam core conforms to your body's curves, evenly distributing pressure to provide steady, supportive comfort—not a soft, sinking feel—for prolonged sitting.

【Enhanced Support for Multiple Settings】As an XL, extra-thick support cushion, it focuses on delivering upgraded stability for larger seats. Whether for a big office chair, a car seat during long drives, or a wheelchair needing additional pressure relief, it offers more complete coverage and stronger support.

【Portable & Washable – Important Note】Includes a convenient carry handle for easy portability. The cover is removable and machine washable for simple maintenance. Please note: Memory foam is temperature-sensitive; it may feel firmer in cooler environments and will gradually soften and conform as it adjusts to room temperature and body heat.

【Designed for Spacious, Stable Comfort】The core value of this product lies in "greater coverage area" and "more secure, non-slip placement." It is designed for users seeking a spacious sitting feel or those using larger seats, providing a solid solution that stays firmly in place and offers comprehensive support.
