In-store only, IKEA retail locations offer the KARLSO 8.5-Foot Hanging Umbrella
. (The link is for reference only; you must visit an IKEA store to purchase this item.) It's $61 under the lowest total price we could find for a similar umbrella elsewhere. Sales tax is added where applicable. It features a 118" diameter, water-resistant fabric, crank, and more. Note that you'll need four concrete blocks (or other similar weights) to complete the base.
