QYILAY Car Memory Foam Seat Cushion — 2.8" Wedge Height Boost, Non-Slip PU Leather

QYILAY Car Memory Foam Heightening Seat Cushion lifts the driver by about 2.5 inches with a wedge-shaped memory foam pad for improved sightlines and more comfortable posture behind the wheel.

If you find yourself stretching to see over the steering wheel or settling into awkward positions during drives, this seat cushion is made to add height and ergonomic support without altering your vehicle. The cushion pairs a high-density slow-rebound memory foam core with a breathable PU leather cover, a non-slip base and a slim profile that fits most car seats. Its design intends to redistribute weight, level the pelvis, and reduce the forward slope common in many factory seats.

How does this cushion make driving more comfortable?

The wedge shape corrects the typical rearward dip of many automotive seats, promoting a more neutral spine angle and easing tension across the lower back and neck. Memory foam adapts to each occupant, spreading body pressure and dampening road vibrations for a smoother ride feel.

• 2.8-inch height at the tallest point, creating a 2.5-inch effective boost.
• High-density, slow-rebound memory foam for pressure relief and vibration absorption.
• Wedge profile aligns pelvis with knees to reduce slouching.

Will it stay in place and keep my seat clean?

The QYILAY cushion includes a textured, non-slip underside that grips upholstery to minimize sliding during entry, exit, and turns. Its PU leather outer layer resists dust and spills and can be wiped down quickly, while a hidden zipper makes removal straightforward when deeper cleaning is required.

• Non-slip bottom secures the cushion on most seat fabrics.
• Durable PU leather surface wipes clean and resists stains.
• Concealed zipper for easy cover removal and washing.

How large is the cushion and will it fit my vehicle?

Measuring 18 inches long by 17.2 inches wide and 2.8 inches high, this cushion is designed for a universal fit across cars, SUVs and trucks. The moderate footprint accommodates a wide range of seat shapes without obstructing seat controls or safety features.

• Dimensions: 18" L × 17.2" W × 2.8" H; 2.5" effective height increase.
• Slim wedge contour fits most factory and aftermarket seats.
• Built-in handle for fast repositioning or carrying between vehicles.

What should I know about materials and care?

The interior uses a combination slow-rebound memory foam that returns to shape gradually and absorbs bumps, while the exterior is breathable PU leather for easy maintenance. Expect initial firmness out of the package; allow about 30 minutes at room temperature for the foam to expand and soften slightly.

• 3D memory foam core provides slow recovery and support.
• PU leather cover breathes and wipes clean; avoid harsh chemicals.
• Product firmness varies with temperature—firmer when cold, softer when warm.

Who is this for: Shorter drivers, daily commuters, rideshare drivers, or anyone seeking a modest height boost and improved seat alignment without replacing their car seat. It’s also practical for passengers who want less pressure on hips and lower back during long trips. Backed by a 12-month warranty and customer support, QYILAY’s cushion is a straightforward accessory to make driving easier and more comfortable.
