RUKHS Lumbar Pillow, Back Support for Office Chair and Car, Memory Foam

FULL BACK SUPPORT THAT HOLDS ITS SHAPE: High density memory foam contours your upper, mid and lower back and typically lasts 5 years or more without flattening. Supports up to 300 lbs. Foam feels firmer in a cold room and softens as it warms to you.
LONGER STRAPS THAT DO NOT SNAP OR SLIDE: Two adjustable straps with a locking buckle hold the cushion on office chairs, gaming chairs and car seats, built longer and stronger than the short, same length straps that make rivals slide down within months.
FITS OFFICE CHAIRS, GAMING CHAIRS, WHEELCHAIRS AND CAR SEATS: Measures 18.1 x 16.6 x 5.5 inches, best for adults from about 5 feet to 6 feet 2 inches tall. Also works as lumbar support for car seats, SUVs and trucks on long drives.
STAYS PUT WHILE YOU MOVE, TWIST OR LEAN BACK: The anti-slip backing works with the dual straps so it will not slide down every few minutes. Needs a solid backrest to strap onto, so it is not recommended for sofas, recliners, or narrow folding chairs.
BREATHABLE COVER THAT UNZIPS AND WASHES: The honeycomb mesh cover keeps your back cool and dry during long sitting, unzips for a machine wash, and uses low odor foam, ready fast once it expands from its vacuum sealed packaging (24 to 48 hours).
