  • Flexible Pool Pillow
Style: Classic Size: 4' X 8'
Handy dandy pool pillow to keep the pool cover up off the surface of the water. This works wonderfully when it rains and there is strong winds to keep dirt and debris out of my pool. Great size fits well for my 12x30 above ground pool. The material is thick and hasn't deflated with use. I like that i can tie it to the pool frame to secure in place. Very satisfied with this purchase. ... show more

  • Cheap pool pillows
Style: Classic Size: 4' X 4' 2-Pack
These are ok. I’m not a fan of the valve stem connection. Not as easy to air up.

  • Good price, seems to work
Style: Classic Size: 4' X 4'
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.

  • Just don't work
Style: Classic Size: 4' X 4'
pretty much a wast of money. I got them from two sources on Amazon and they were from different manufactures. I got 11 of them. both kinds had these cheesy hard plastic valves. It was hard to get the inflator in and near impossible to close the fill port. Mind you I am big and strong, lie 6'6" 240# strong. you might fill these to be hard and tight, but the will lose quit a bit of air closing the cap. I tried putting shortening on the cover to ease insertion and help seal them. After they are closed they are full but not firm. I would say 90% of them leak. About half will be pretty much flat within a week. One of them came new out of the box with a slash in it. (the vendor promptly replaced it) This is a product that you want to stay blown up all winter. You would need to get at least three times what you need have enough functional ones to last the winter. Further if you use these on an in ground pool and drain to to below the skimmer box as recommended They barely raise the pool wither cover. They have so little buoyancy that rain will sink the cover all around the pillows. I can't image they work better on above ground pools. I ended up making an arched support from 1" plastic conduit and cross fittings. That works pretty well. You make the pipe length about 1 " longer than the pool is wide. You can arch them by making pieces to fit the edge of the pool or running a cord across the ends and tightening it. ... show more

THE PILLOW ISNT REALLY LARGE ENOUGH IN MY OPINION.... WE HAVE A 24 FT ROUND POOL. ALSO , THE PILLOW HAS A RIP/CUT WHATEVER U WANT TO CALL IT, RT BESIDE THE SEAM . WE WENT AHEAD AND BLEW IT UP AND ARE GOING TO SEE HOW IT WORKS. HOPEFULLY THE AIR WILL STAY IN, IDK. I WOULD HAVE SENT IT BACK BUT WE REALLY NEEDED TO GET THE POOL CLOSED UP., AND IT WASNT SUPER EXPENSIVE AT ALL. IF IT DOESNT HOLD UP ILL LET U KNOW. FINGERS CROSSED. OTHER THAN THE SPLIT NEAR THE SEAM I THINK IT WILL B OK :) .... ... show more

  • Greatest deal if you need more than one save on shipping.
Style: Classic Size: 4' X 4'
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

  • Nice quality pillow
Style: Classic Size: 4' X 8'
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
