Should I Buy It?

However, there are some reports of quality issues that may make other options worth considering as well.


  • Nice quality pillow
Style: Classic Size: 4' X 8' (Blue)
Some have said this does not hold air. I've had no problems. However, I think the reason some don't hold air is because you have to be REALLY meticulous when seating the cap. It has two seals on it, and if you don't get it pressed down just right, air will leak. A little extra effort and there shouldn't be a problem. Also, when inflating it, I couldn't get the flap to open up...almost like it was sealed shut. Just push around the edges of the flap with a rounded tip object and go in a circle, and eventually it will open. Oh, and don't even try to inflate this by mouth. I used an air compressor and it still took a while. I inflated it almost to capacity and then deflated it a little to allow some room for expansion and contraction. Has been fine so far. ... show more

  • Good price, seems to work
Style: Classic Size: 4' X 4' (Blue)
Exactly as described. 4 stars because it has deflated a little in 24 hours. It may be stretching of the vinyl. I will rate again after a few weeks to make sure it worked.

  • something went arong
Style: Classic Size: 4' X 4' (Blue)
This product failed in the first winter use. I blew it up and put it straight into the pool. It was not leaking when I originally floated it so I don't know what could of happened except it was defective in some way

  • Happy with purchase
Style: Classic Size: 4' X 4' (Blue, 3-Pack)
These Air Pillows were worth the price and worked well for our above ground pool. It appears they should be sturdy enough to withstand the winters for hopefully at least a couple years. They possibly could last longer but usually when we use this type holes appear after several years, you can always patch. ... show more

Style: Classic Size: 4' X 4' (Blue, 2-Pack)
Good size, I bought 8 of these pillows to fill my 18ft above ground pool for the winter. I used a non mesh cover, so wanted to make sure there was a base between the water & the cover in case we got a heavy snow fall. Two of the pillows did not hold hair, but the other ones are still working strongly. Definitely a good price for a set of 2 pool pillows though. ... show more

  • Greatest deal if you need more than one save on shipping.
Style: Classic Size: 4' X 4' (Blue)
They got here super fast Fedex and the shipping was the same for two as for one. So buy two even if you don't need it right away. They are actually 4FT in Diameter not 4x4 but they are good quality blue plastic with holes for ropes on two sides. They are about 3ft high off water as I didn't go crazy inflating them only firm not hard. No instructions for filling with air. 1" fill hole + cap and inner check valve flap allows use of a shopvac exhaust to fill or a big compressor by shoving the blow hose nozzle into the flap. If you don't have either you will take forever to blow into it with your lungs. It is 4ft diameter not 4x4ft if that makes a difference to you? Has holes for lashing on two sides with ropes. Two units work perfectly as discribed in our 12 x 20ft above ground pool. I'm using a porous cover as live in FL and only want to keep the leaves out and avoid pumping rain off solid cover every month. I use spring clips instead of the wire to keep the edges under tension. These were a great value with the combined shipping!!! Easy to inflate. Easy to push under the cover with the skimmer screen and pole. I didn't use ropes yet as figure they will stay put with tension of cover. Sit virtually on top of the water so get a high slope to outer edges. ... show more
