I would say you would probably find the best lift chairs at a furniture store. They would probably have better quality items than items you see online.
I agree, don't buy one with "leather" or certainly not "bonded leather". Most items they are just pleather and will peel.
Here are all the ones from third party sellers on Sears.com: sears.com/search=lift%20chairs%20with%20heat%20massage
Hope this helps!
