The details did not explain. There are two (one larger) inflatable pillows that you blow up then insert into the two sleeves at the top and bottom of the hammock. This is excellent if you have limited storage space and need to deflate to transport. I may try inserting shortened noodles. It is lovely for floating while partially submerged so as not to get too hot. Stable enough I can read while floating. It is a little short for tall people. I am 5'7" and I wouldn't want it ant shorter.
I use this pump to partially inflate the pontoons on my inflatable boat. This pump is very fast and brings the pontoons up to about 1 psi very quickly. I then switch to a true high pressure pump to finish off the chambers with 3 psi. This pump has enabled me to cut my inflation time in half. Great for float tubes also.
Very good price.. It arrived quickly and easy to wrap for Christmas. My husband loves this. It was easy to inflate with our home air compressor. It is perfect for my husband and the puppy to float in the pool.
You do have to get yourself centered on the float, but then it is so comfortable. Floats great. Took a little work to get it assembled -- yes, you have to put the cover on the float portion and inflate it.
