Do you carry replacement sling covers for patio chaise lounges without the frame?

Check the end caps of the aisles. A lot of seasonal stuff are thrown there and marked down in price. Sometimes you'll find them with the pop ups and patio sails. If not you can always get them on line. On line look under the SPECIALS & OFFERS tab and then click on special buys and overstock. Might get lucky

Try shopping for that online. Patio furniture is seasonal. So online will have more selection.

You might try Home Depot webpage online. The webpage has much more items especially for outside patio items then they carry in store. If not, try Lowe's.
