It really is the most comfortable meditation bench.  I’m obviously biased, but I listened to all the friends and strangers who sat on all the prototypes and prior efforts over the years. And the METTABENCH™ is what I came up with.  If you want to buy one they’re for sale on Amazon.

If you’re new to meditation though, you should experiment with different types of sitting postures till you find the one that works best for you.  You’re going to spend a lot of time in it, and it’s important that you choose a style that best accommodates your body.  I still prefer half lotus and only use a seiza bench when my knee is acting up.
