Combined with an ergonomic beveled edge design, this high-density memory foam cushion helps minimize pressure on your coccyx, tailbone, and sciatic area, offering soothing comfort for long sitting hours or post-surgery support - 【Improves Posture & Reduces Back Strain】 Turn any hard chair into an ergonomic seat. The thoughtful beveled edge design encourages a natural, upright sitting posture by supporting proper pelvic alignment. This helps distribute your weight evenly, reducing strain on your lower back, hips, and thighs - whether you're working 8+ hours at a desk or on a long drive - 【Medium-Firm Support That Won't Flatten】 Please note: To provide proper ergonomic support, this cushion is intentionally designed with a Medium-Firm feel, NOT a plush, sink-in feel. If you prefer ultra-soft foam, this may not be the right fit. Unlike soft cushions that quickly bottom out, our premium memory foam holds its shape all day, providing stable, resilient lift that won't flatten over time - 【Extra Large & Perfect for Short Individuals】 Measuring 18.5" x 16.9", this cushion accommodates adults comfortably while providing the perfect 3.35-inch height boost. Ideal for short drivers needing better road visibility, seniors needing extra height to transition in and out of chairs, wheelchair users, and anyone seeking reliable support for office chairs, car seats, dining chairs, and travel situations - 【Non-Slip Rubber Base & Easy to Wash】 Say goodbye to constant adjusting! A sturdy anti-slip rubber bottom locks the cushion securely in place, so it won't slide around on your office chair, car seat, or wheelchair. The breathable mesh cover features a durable zipper, making it easily removable and machine-washable for hassle-free hygiene ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D1V6GC8J | | Age Range Description | Adult | | Best Sellers Rank | #1,742 in Office Products ( See Top 100 in Office Products ) #16 in Back Cushions & Seat Cushions | | Brand | TranquilRelax | | Brand Name | TranquilRelax | | Color | Grey | | Customer Reviews | 4.2 out of 5 stars 2,018 Reviews | | Fabric Type | 100% Polyester Mesh Cover | | Fill Material | 100% Premium Memory Foam | | Item Dimensions L x W | 16.92"L x 18.5"W | | Item Firmness Description | Medium Firm | | Manufacturer | TranquilRelax | | Manufacturer Part Number | MPN-TR0001-L-GE | | Material Features | Breathable, Moisture Wicking | | Material Type | Memory Foam | | Material Type Free | Formaldehyde Free, Latex Free | | Model Name | MPN-TR0001-L-GE | | Model Number | MPN-TR0001-L-GE | | Number of Pieces | 1 | | Pattern | Solid | | Product Care Instructions | The memory foam core is not washable.
