A plush, fluffy texture makes the cushion feel inviting while still providing stable support.
HOMBYS 27.5x18x5 Back Cushion
This cushion matches standard sofa dimensions with a 27.5-by-18-by-5-inch profile. It continues to use shredded foam filling for a comfortable balance of support and softness.

This larger back cushion continues the shredded foam approach, designed for couch backrests and multiple lounging surfaces including beds or floors. The filling offers a responsive yet soft feel, aligning with the natural curve of the back to reduce pressure points. The breathable fabric is comfortable against the skin, promoting airflow and long-term use without overheating. It’s well-suited for bigger seating arrangements or shared living spaces.

Tanyoo’s back cushion features a dual-layer foam design with a gel memory foam top layer for cooling comfort, plus a high-density foam bottom layer for stable support.

The pillow is described as orthopedic-grade, with an emphasis on reclining comfort and spinal alignment. The size remains suitable for most recliners and sofas, with a focus on long-term durability.
Buying Guide: How to Choose the Right Couch Back Cushion
- Size and fit: Measure your sofa’s backrest and the area you want to cushion to ensure a proper fit. Cushions ranging from around 26-31 inches in width fit most standard sofas, while thicker profiles (5 inches) provide more support but require room for placement.
- Fill material: Shredded foam and memory foam blends offer different levels of contouring and rebound. Shredded foam tends to be softer and more breathable, while memory foam provides firmer support and better shape recovery.
- Support level: For back pain relief, look for cushions designed for lumbar support with a curved contour. Dual-layer designs with a memory foam top often balance softness with stable support.
- Breathability and fabric: Choose fabrics that are skin-friendly, breathable, and easy to clean. Breathable covers help prevent heat build-up during extended seating.
- Maintenance: Removable covers that are machine-washable simplify upkeep. Check care labels for washing instructions to extend product life.
- Placement flexibility: Some cushions work well on couches, beds, or chairs; others are specialized for recliners. Consider whether you want a single cushion or multiple cushions for sectional setups.
- Durability: Look for high-quality stitching and robust fabric, especially if the cushion will see daily use. Durable fillings resist flattening and maintain shape over time.
