Not really a bolster at all. A bolster should have support, that's the entire point of it. This came packaged folded in half with all the stuffing clumped together in the ends, then vacuum packed. I took it out and tried to redistribute the clumps and let it sit for 24 hours. It didn't improve. This provides absolutely no support and because it has so little filling, it doesn't really look that nice either. This product wasn't designed to be a useful, quality product. It was designed to be as cheap to ship as possible.
