I have L2,3,4,5 and S2 problems and searched too. I found these:

Haven't bought any yet but did go to a store and try them. Felt great for the short time I sat in them. I like the individual reclining sections in the sofa. They are expensive, the Paradise high back sofa in the leather I like is $5195, love seat $3995 and chair is $2695. Not sure I'll ever be able to afford this stuff.
Here's a local dealer for you:
