I love, love, love these ottomans. I used the flimsy pump to blow them up two months ago and have not had to add any air to them. Both have are located on our uncovered deck so getting all the elements and have held up well. They are light weight so when I know a big storm is coming in I put inside our screened in porch. These are used as ottomans, tables and seats. There has been slight fading - but for $30 - I am ok w/that. The great thing is the zipper hides away, the handle on the side makes for easy pick up and moving. After blowing up, inserting and zipper the first one I learned blow up to almost full, insert w/plug facing down and where zipper will end, then insert, and zip - but when zipping guide w/your finger on the inside so it does not grab the material and get stuck. Putting the plug on the bottom of the ottoman by where the zipper ends allows easy access incase you need to add more air once inserted. Get these ottomans - they really are fantastic.
