To be on the safe side, buy a slipcover made specifically for lift recliners. There are two types of lift recliners. One lifts from the base and tilts forward. A larger lift recliner telescopes up from the base, then tips forward. The lift recliner sits on a mechanism, so you’ll also want to have a slipcover with an elasticized bottom that fits snugly under the chair, but that doesn’t interfere with the mechanism.
