TranquilZone memory foam seat cushion for office chairs — Black, patterned-core support for tailbone & posture (17.7×16.1×2.95")

TranquilZone's memory foam seat cushion is a firm, patterned-core chair pillow designed to distribute weight evenly and reduce pressure on the hips, tailbone, and lower back during long sitting periods. This cushion pairs high-density, CertiPUR-US certified memory foam with a patterned internal core to create steady support that holds its shape longer than lower-density foams. The removable, breathable cover with a smooth-glide zipper helps manage heat and is machine washable for easy care. Sized to fit most office chairs, car seats, wheelchairs, and stadium seats, the pad includes a non-slip base and a built-in carry handle so you can move it from desk to car to plane.

How does this cushion improve comfort during long workdays?

The TranquilZone cushion reduces pressure points by using a patterned foam core that spreads weight across a wider surface. Its firmer density resists sinking so your pelvis and spine stay better aligned while seated.

• Patterned core for even weight distribution
• High-density memory foam that maintains shape
• Reduces localized hip and tailbone pressure
• Improves seated posture during long sessions

Will this fit my office chair, car seat, or wheelchair?

Yes — the cushion measures 17.68" x 16.10" x 2.95", a common size that fits most office, dining, car, and wheelchair seats. The non-slip base holds the cushion in place so it won’t slide around on typical upholstery.

• Universal dimensions for broad compatibility

• Lightweight with a built-in handle for portability
• Suitable for home, office, travel, and stadium use

How do I care for the cushion and cover?

• Spot-clean foam; avoid machine washing or dryer heat
• Cover fabric is OEKO-TEX STANDARD 100 certified
