This pillow arrived in a tightly plastic wrapped, square-ish package. I honestly did not think it was the bolster pillow...but it was! I removed it from the packaging and attempted to fluff it, without much success. I let it sit overnight and it did improve, but it is not yet in a cylinder shape. I am not holding out much hope, but I may toss it in the dryer for more fluffing. Meanwhile, the pillow color is exactly what I wanted, which is great. I am using it inside for my lounge area. It is a Sunbrella fabric, too, so I know it will be durable. The cover is zippered, so it can be removed to be washed, if necessary. As of now, its shape is more of a slightly flattened cylinder, but when it is on the chair, I do not notice as much that it is not quite round!. Jani. Glendora Ca. Tue Apr 28 2026
