  1. Easy to install Review by David

    Easy to install. Good product saves time and money. The plastic is tough and should last for years unless you drag the chairs over concrete instead of lifting.

  2. Work great Review by Paul

  3. Good product Review by Grammy

    Unfortunately it was not the right fit (Posted on 6/22/2018)

  4. Happy camper! Review by Gaijin

    I had to crimp the legs of our chairs a little bit. The fit was very close, but not perfect. I figured I could modify the feet if needed. Other than that they work great. I figured there are infant sizes of chairs on the market. If the crimping didn't work I would have used silicon to glue them in. I am happy they have saved my new Terx deck (Posted on 5/26/2018)

  5. Overall satisfied (4 stars) Review by Happy123

    Product was a bit undersized for my chairs. I was able to compress the tubing on the lags to acquire a tight fit. The product should serve its purpose just fine. (Posted on 5/22/2018)

  6. works for my needs Review by Purchaser

    as described but it was just a hair smaller than what I needed for my chair but with some ingenuity, I got it to work well. (Posted on 5/16/2018)

  7. Product was as described Review by fixer upper

    product was as described but was a bit small for my application but with a little silicone worked and was presentable (Posted on 5/9/2018)

  8. Excellent item Review by Jaybones

    Purchased for replacing broken flat style inserts on the tube style legs of our sling patio chairs. The items were loose in the tubes until a simple squeeze with a pair of pliers which allowed me to lightly pound in these replacement inserts. They fit perfectly now and being domed, look like they should last longer then the originals.
    The description should read Oblong design and not rectangular, which would help describe the actual design of the piece. (Posted on 5/3/2018)

  9. Perfect! Review by VRinger

    I have ordered these inserts from you before and they fit perfectly. They are just what we needed to replace the originals on our patio chairs which wear and ultimately break on our pavers. THANK YOU for carrying these critical little items :) (Posted on 4/16/2018)

  13. Fit as advertised Review by John y

    The product fit as advertised, whether it last will have to be seen (Posted on 10/19/2017)


    These fit into the advertised dimensions of the chair leg but do not grip because the plastic is just too hard and does not flex. (Posted on 8/24/2017)

  15. product was correctly described Review by Dotty

    Product was correctly described. I inserted it into bottom of chair and it lasted for a little while but then slid up into chair leg. (Posted on 7/11/2017)

  16. Perfect fit Review by Rick

    This was exactly what I was looking for. (Posted on 6/20/2017)

  17. Bad Description Review by the general

    From the description of this product it appeared that it would fit over the leg of a bar stool. There was no mention of dome insert, thus the confusion! Also, it costs more to return than the product cost, so the customer is out! (Posted on 6/19/2017)
