Question: Where do you put your feet? Just bend your knees, or is there a foot rest? Also how hard is it to get on and off, for a 60 yr old Aunt, who is game for fun, but, not as flexible, as she used to be.
Document: i think this is the greatest tube around and it is very freakin' fun. It may seem easy at first but if you have a father like mine, it can be extremely hard with a friend leaning on you and the force of a really hard turn. GREATEST THING EVER'!!!!!!!!!!!!! !
I purchased Big Mable for our family to be something which can work for people of all ages. It is great for small children (I used with my nieces ages 6 and 7) as it is EXCEEDINGLY stable with lightweight people on board. I had a difficult time even getting them out of the wake without putting in  a lot of effort. The kids also enjoyed riding the tube "Chariot" style. Both traditional and chariot style the tube with incredibly stable.
Very Happy with this purchase, heavy duty, rides great, we put little kids on this and it does not flip. This unit is very stable in the water even at high speeds, if you are looking for something you can flip around this is not it...if you want a stable ride for kids this is your towable...BTW we also tow adults and everyone loves it.
Not as fun as the old Big Mable but it works.. Kids have a blast on this tub all the time.
Friends of mine have this inflatable and love it so I was very excited to get it for my kids to try. I thought the tall back would be great for beginning tubers. Unfortunately, both times I have used it with them, the front end plows under water and tips over with the kids trapped underneath. They are now totally afraid to go tubing again. I don't know what the issue is but I would not recommend this to anyone. It is simply not safe!
Most fun we've had in a long tIme on the lake. My 6 year old grandson loved Big Mable, it's very kid friendly and very well made.
I ordered this so we would have something for our 5 year old grandson to do when we took him to the lake. He and the entire family are having lots of fun riding Big Mable. It is different than the round tubes you lye on but just as much fun. You sit instead of lying down and it's more comfortable. Would definitely recommend to anyone.
We are on our 3rd Big Mable - flat out wore the first one out, 2nd one got stolen off the dock, even though it was locked up, now having great fun on #3. Highly recommend this product because of its versatility in levels of thrill for young & old - can give a comfortable tame ride or a crazy fun roller coaster for those more adventurous. Buy it!
If you want maximum protection for your skin, wear long pants when kneeling. Longer bottoms may also be a good idea for sitting too since regular swimsuits may ride-up. Gloves may be a good idea for extended rides, or you'll risk blisters.---Overall, the Big Mable is an awesome tube. It handles all sorts of riders, it has held up well (over three months with at least 2 weeks of heavy use/abuse), and it is very very fun.
This is sooo much fun! My family has such a good time on this! It is easy to get on, and easy to hook up to the boat. A GREAT family time! !
