The best brand of leather recliner is the one that fits your budget and style. Most leather recliners are made out of the same materials, so the quality is going to be pretty much the same but the price will vary depending on the brand and the materials that they use.
In terms of what brand makes the best recliner, that comes down to personal preference. If you’re looking for a more affordable leather recliner, then I recommend looking at Bassett or La-Z-Boy.
