That's than 800 lbs. more strength than the webbing mountain climbers have been depending on for many years.
It's also a better than 14 to 1 safety margin, 10 to 1 is a lot, and 5 to 1 is quite acceptable for applications where there will be no shock loads.
One thing though, while you'll retain 80% or better strength with a splice, as opposed to a knot, you should also consider the radius of what ever your attaching to. Smaller radius' = more stress.
You won't be jumping up and down in your bed will you?
This is from OSHA,
1910.269(r)(7)(i)
Climbing ropes shall be used by employees working aloft in trees. These ropes shall have a minimum diameter of 0.5 inch (1.2 cm) with a minimum breaking strength of 2300 pounds (10.2 kN). Synthetic rope shall have elasticity of not more than 7 percent.

You've got to be careful what you listen to around here. I suspect a lot of these guys work for some of these manufactures.
Many of them will have you spending 10 times what you need to.
Having said all that, poly-rope isn't very nice to work with in my humble opinion. I like softer more pliable material. But that is a matter of preference not function.
