  • Not a true triangle

    Maybe it was our own fault. We were expecting a true triangle and were planning on attaching it to the patio cover but, due to the angles of the cut it left big gaps between the roof and the fabric therefore not providing as much shade as we had hoped for.

    • How did the color on site compare with the actual product? Excellent
    • Please tell us about the quality of the product. Good
    • How accurate was the on site description of the product? Average
  • Just what I ordered

    The sun shade is perfect and very nice looking, I especially like all the hardware included which allows me to adjust the shade easily to get the perfect shady patch. Great quality and materials of construction. Can't say much about durability since I have only owned for a couple of months but I hope it last because its a pretty handy and portable sun shade.

  • Great Value

    Great product. The only negative is the rope sent with the mounting hardware is a bit weak. I replaced this with $4.00 worth of stronger cord from the hardware store. I will buy another one. Walt

  • Very good solution for a sunny patio

    package lacks installation instructions; must go to internet to get more clear instructions and how or where to get the poles required

    • How did the color on site compare with the actual product? I prefer the color which is granite (very dark grey) not black as stated
    • Please tell us about the quality of the product. have not installed yet it looks like the quality is great.
    • How accurate was the on site description of the product? description is okay but package lacks installation instructions

  • Would not recomend

    I ordered this because other reviews said it was great and easy to assemble. Granted it does come with directions and all the tools, but it was no where near easy. The shape is not a 90 degree triangle. Not sure what shape you call it but getting it to cover a simple corner in the yard is near impossible. Add that to the fact that the part of the yard I want to shade is insanely hot, spent two days with help trying to get the thing up and quit. Not worth it.

  • Very good

    We like the style of the shades and they really do the trick of giving of some shade on the deck. It is a really a unique look. We are using 2 medium shades and the sizes work just great! The only downside is the rope it came with. The white nylon rope looks too much like tent rope and not very attractive. We are in the process of finding something less "campy". Even a darker color would be better. That aside, we are enjoying the sails.

  • Quite Small

    We bought this for camping and it is quite small. It was OK with keeping rain of the area it covered.

how large do the polls have to be if I use wood. 4 by 4 or larger.for either a medium triangle.or a large square sail. rosshansen on Apr 28, 2013

Answer This Question

Thank you for the opportunity to help you today rosshansen with the Medium Triangle Sail Sun Shade. We are not exactly sure of what you are trying to accomplish on the installation of your shade but as we can see if we are correct in assuming what you are doing a 4X4 should be sufficient for your application. We hope this was helpful and thank you for shopping Overstock.com. overstockcustomercare1 on May 3, 2013
I've used 4 x 4. My space was unusal so I placed posts where appropriate. the triangle is so flexible. I hung a medium and small triange in a rectangle area. I had a hard time adusting by myself until I tried using a few bungy cords. this allowed me to be flexible and spontaneous about how I could place my shades. I have high winds in my area but the shades ae so easy to take down and the wind moves around them quite well. the posts really don't need to be overly sturdy or even. pamelawk on May 21, 2013
