Question: These stools didnt come with instructions, I got them together but they are not hydraulic. Am I missing something??
Document: These stools were easy to put together. They complete our home bar. The adjustable height via the hydraulics are a feature I wanted in such a stool and this delivers.
Easy to put together, looks nice in my contemporary home theatre and true to the picture. Most importantly excellent customer service from the company. I bought another bar stools and needed only 3(not an even number) and they were able to ship me 3. Very happy with them.
I bought these stools last Christmas for my husband to use in the garage at his &#34; bar &#34;. We didnt actually start using them until mid-January 2014...loved them .... at first...then, about a month ago, noticed the arm supports on one of them was getting loose. We checked underneath the seat where it is welded, but couldn't see anything wrong.
These look really good in my kitchen and exactly what I had been looking for to replace my old bar stools. They are comfortable and adjustable.
These stools were just what I wanted, upgrading grand-twins from the Easy Diner clip-on chairs to counter stools, plus they are adjustable! PERFECT!
They arrived on time. That's is the only positive thing I can say about the stools. They are flimsy, feel unsafe, and you feel like you are sliding out of them. The foot rest was a half circle, not a full circle as shown in the picture. The seller issued a return authorization, and paid for the return postage only because the foot rest was different than in the picture shown. Would not recommend these stools.
I have had them for 1 month  and so far they  are grate and just exactly what I wanted thanks
I'm not happy with the black vinyl on the chair arms as it keeps slipping and turning.Other than that I am very pleased with this bar stool. Looks good and is comfortable.I would recommend it.
they are nice looking , my little kids like them. but they seems to lean you too far forward to be comfortable. I think its dues to their small bases and they don't want you to tip backwards so they compensated by leaning the seat forward.
Great product. Little bit issues in understanding work intsructions because they were 2 springs extra in all parts that came in to be assembled. Soon I realized so it was OK. Overall product is great addition to my living room-kitchen
Answer: Hi Cynthia, I had the same problem but realized I didn't take the plastic caps off of the metal rod that you push the seats onto. These need to be removed first and discarded. Hopefully that will fix your problem.
