You can't beat having a hammock. Relaxing in the back yard while the kids play (or are at Grandma's house), there's nothing better. This Viviere Double Hammock with Stand at Amazon Canada is quite a fab price right now, too. It is on sale for $114.99 down from $212.76 including shipping and handling. There are a few colours to choose from.
The Double Hammock comes in 6 colour options that are all fun and unique. I would go with Salsa to match my back yard decor - but I bet they are all equally comfortable.
The best thing about the Double Hammock is that it is meant to hold multiple people comfortably. So you can read to the kids, relax with the hubby, etc. and not have to worry. The weight restriction is 450 pounds - so get the entire family on there if you want to.
You can also pack this hammock up and bring it to the cottage with the included hammock bag. My backyard doesn't have two trees, so this type of hammock is perfect. It can literally be set up anywhere.
