Question: Can I purchase replacement springs
Document: The carton was missing the extra set of springs that were supposed to be included with the chair. Nobody to contact for replacement.
I would also suspect the springs are not replaceable--this is sold as a unit without the option of replacement parts.Any complaints aside, I love this. It's a real, useable, spring-loaded Pilates chair; it was dirt cheap for what it is;  it folds up into a very small space, for the cost of about five private sessions in a studio. Impressive.P.S. Just read the instructions first.
There are two Mailbu chair models. The original with standard springs and the Malibu Pro* that comes with standard springs but also allow you to purchase stronger ones later. 25"W x 32"D x 24"H chair footprint.The Pro chair is sturdy. Comes with 3 DVDs and a wall chart. First DVD is 20 minutes-just learning basic positions.
I am so happy with my purchase of the malibu exersice chair and dvds. It is everything I wanted it to be. Like New. Thanks so much.
The product was broken when it arrived and had to be returned. I requested a replacement but was told that it was out of stock.
MVe, Stott's, and even Rael Isacowitz also have DVD's that are compatible and that I will be considering purchasing.All in all, this chair was a good purchase for me because I love pilates and can't afford individual lessons in a studio.
I bought this Pilates Malibu chair and am very happy with the purchase. It's sturdy and well built. It's not a professional chair, but for 1/3 the price, its a great substitute for your home gym. I'm happy with the chair and would recommend it. I haven't watched any of the videos, but the enclosed chart shows you how to do many chair exercises
A year ago I had a knee replacement done, it didn't go well. I have taken over my physical therapy by purchasing a Bowflex climber and a Malibu Chair. I have had my bowflex climber for nearly a year, but I just ordered my chair last month. But it never came. it was ordered thru Amazon.com with JWWEB... he/she was great.. I e-mailed her/him?
Have it for about a month. Really enjoying it. Had a knee replacement  and have no stress on my knee while doing the exercises. Would highly recommend it for someone who had knee injuries.
I purchased the chair to work on flexibility. I have taken pilates classes and enjoy the versility and the breathing exercises. The chair met my expectations in quality and performance. The one thing I don't like is the way the pin fits in the foot pedal. It seems loose, but works adequately. The videos are good and very safety minded. I would have liked a more advanced video with less time spent on instruction but the entire purchase was a pleasing one. Thanks Amazon!
