One can sleep in any position with this hammock/tent. The mat is held tight by force multiplying climbing strength webbing, and is quite stable and taut. The tent is capable of being used on the ground as a 'normal' tent if there are no trees around. One downside is that I don't think anyone over 6' tall will like this tent. I'm 5'10" and fit nicely.
The AERIAL A1 is lightweight tent with a flat, stable sleeping surface that can be suspended between two trees like a hammock. Get off the ground with the AERIAL A1 Tree Tent / Hammock

The only drawback in my mind is the length of the end bars which spread the mat. The weight is around 5 pounds if I recall correctly. For storm protection I suppose the tent cover is most protective, but I prefer to use the net tent and a tarp for 3 season use, both for visibility and ventilation.
Here, in the Adirondacks, you can see that the packed hammock is quite long. Annoying a little, but for canoe camping... no big deal.

Like all hammocks I suppose, it's great for uneven ground. The orange sheet below is a gear storage hammock. It works, but stuff falls out if you're vigorous getting in and out.

My favorite configuration: used with net tent and a tarp. Just adjust tarp up or down as weather dictates.

And, with full tent cover on a pretty steep side hill installation.
