Excellent size and goods that it comes in 3 parts. The angled corner piece is great. Conformable not too firm, not too soft. Material seems robustdurable. Giving it a 4 star instead of 5 because there is some undulation of material after use, although likely within normal limits. It also took nearly 5 months to receive. When I ordered it - it was not stated as backordered, but as soon as I purchased it that’s when I received word it was backordered. So a bit of deception there.
