My grandparents gave us one of these chairs. Not only is it really comfortable but:

1. My daughter loves to nap in it with me;
2. I love to nap in it.

If you have a spot in your yard to hang one, I think it’s better than a regular hammock. Amazon has a bunch too, but I can’t vouch for any of those brands.

Pro tip: mount with an eye bolt and hang with a caribiner for easy winter take down.
