Betty's Upholstery Furniture in Santee's Prospect Avenue industrial corridor reupholsters residential furniture, automotive interiors, and marine cushions from Suite K at 10439 Prospect Avenue. The automotive division restores headliners, seat covers, and door panels, and interior-trim timelines often run alongside collision repair schedules at Fix Auto Santee at 10806 Prospect Avenue. Established in 1989, the operation has maintained continuous service on the Prospect Avenue and Woodside Avenue industrial strip that defines Santee's secondary commercial zone. Residential commissions include antique-chair restoration, sectional sofa recovering, dining-chair re-padding, and custom boat-cushion fabrication using Sunbrella and other UV-resistant marine-grade textiles. Home-renovation clients coordinating full room overhauls with contractors at Blueprint Renovations on Prospect Avenue route upholstery work here to match new cabinetry and flooring palettes. The shop cuts and sews from bolt fabric in-house, maintaining a library of leather hides, vinyl rolls, and woven textiles that support single-piece restorations through full fleet vehicle interior programs.
