EDIETH Height-Adjustable Seat Cushion 15.7x15.7x4.7 in — Breathable Nylon Mesh Memory Foam Support

The EDIETH height-adjustable seat cushion is a 15.7 x 15.7 x 4.7-inch ergonomic memory foam pad with breathable nylon mesh and removable filling for customizable support in cars, offices, and outdoor seating.

This improved model from EDIETH blends firm PP memory foam with a reinforced, ventilated nylon mesh cover and a user-adjustable height option. It’s engineered to distribute weight evenly, resist flattening over time, and stay cool during long sits. The updated stitching, extra filling on delivery, and a compact footprint make it a versatile companion for commutes, desk work, travel, or outdoor activities.

How does the adjustable height improve daily comfort?

The adjustable height lets you tune the cushion thickness to match your chair, leg length, or posture needs. You can remove some of the included filling to lower the profile, or keep it full for added lift—helpful when seats feel too low or lack padding.

• Removable filling for personalized height and firmness
• 4.7-inch max thickness for extra lift without bulk
• Works with a wide range of seat types: car, office, outdoor

What materials and construction keep this cushion durable and breathable?

The core uses PP memory foam selected for balanced resilience—enough firmness to support without excessive sink—while a reinforced nylon mesh cover promotes airflow to reduce heat buildup. Stitching at the zipper is reinforced to prevent seam failure and extend the product lifespan.

• PP memory foam core resists long-term flattening
• Breathable nylon mesh cover increases ventilation
• Reinforced zipper stitching for greater durability

Will this cushion fit my car seat or office chair?

The cushion’s 15.7 x 15.7-inch footprint is compact enough to sit on most car seats and office chairs without interfering with controls or armrests. Its low profile and slim edges slide easily under seat covers and remain stable while you move.

• Compact square shape fits most vehicle and chair surfaces
• Slim edges prevent bunching and maintain seat cover fit
• Stays in place during normal driving and daily use

How do I care for and adjust the cushion?

The mesh cover is breathable for everyday use and can be unzipped for spot cleaning or to access the filling. If you prefer a lower cushion, simply remove some of the included filling material; to refresh loft, tuck the filling back in evenly.

• Unzip cover for cleaning and filling adjustment
• Spot clean mesh; avoid machine soaking to protect foam
• Redistribute filling to maintain even support
