Measuring approximately 17.5 by 13.7 inches, the cushion fits most chairs, including office seats, car seats, and wheelchairs, ensuring versatile usage. The non-slip rubber bottom prevents sliding on smooth surfaces, and the soft velour fabric cover is removable and machine-washable for easy cleaning.

The QUTOOL Lumbar Support Pillow is designed to offer significant relief for those who spend long hours sitting, whether in an office chair, gaming chair, or car seat. Its memory foam fill ensures a firm yet comfortable support that maintains its shape over time. One of its standout features is the upgraded, lengthened adjustable straps, which help keep the cushion securely in place on a variety of chairs, although it may not be suitable for more casual seating like sofas or recliners.

At a size of 16.9” x 15.5” x 4.7”, it is most effective for individuals weighing between 100 and 200 pounds. The ergonomic design aims to support the natural curvature of the spine, helping to alleviate back pain and improve posture.

The breathable 3D mesh cover promotes air circulation, ensuring comfort across all seasons, and it is removable and machine washable for easy care.

While its high density, thick memory foam provides solid support, its medium-soft firmness might not be ideal for those seeking very firm support.

The Everlasting Comfort Memory Foam Seat Cushion is designed to help relieve tailbone pain and improve posture for those who sit for long hours, whether at an office desk or in a car. It uses 100% memory foam, which offers a good balance of softness and support, described as medium firmness—comfortable yet firm enough to help reduce pressure on your lower back and buttocks. Its ergonomic "U" shape specifically lifts the tailbone off hard surfaces, which can be very helpful for sciatica or coccyx pain. The cushion also features ventilation holes to allow airflow, helping you stay cool during extended use.

Sizing is standard and rectangular, fitting most chairs easily without needing complicated adjustments. The cover is breathable polyester, removable, and machine washable, which makes it easy to keep clean. However, the memory foam itself cannot be washed, so care is needed to maintain it over time. While the product mentions adjustability, it mainly refers to repositioning rather than changing firmness or shape, meaning it may not suit everyone’s exact preferences if you want a highly customized fit.

Weighing about 3.4 pounds, it is portable enough to carry between car and office. This cushion represents a solid choice for those seeking a straightforward, doctor-endorsed solution to improve comfort and reduce tailbone stress during daily sitting, though individuals who need more tailored firmness options or a larger size might need to look elsewhere.
