This contoured foam ring provides back support when sitting for an extended period of time. The puncture-resistant support foam conforms to body contours, effectively reducing pressure point discomfort. The high-density foam retains shape through repeated use, and the polyester/cotton cover removes for easy cleaning. With a maximum weight capacity of 250 lbs., this foam ring is available in three colors in three different sizes: White, Navy, and Plaid in 14ﾔ, 16ﾔ, and 18ﾔ.
