VLUV FAQ I Frequently Asked Questions

There are two main criteria that should be considered:

1. The body height
2. The range of use

1. body height

We offer 3 ball sizes for the following body heights:

BOL 55: approx. 130-155 cms
BOL 65: approx. 155-180 cms
BOL 75: approx. 180-200 cms

Here you can select the ball size that generally fits your body size. Tip: Especially in the border areas between two ball sizes, i.e. approx. 152-157 cms and 178-182 cms, you should rather opt for the smaller size if you want to sit comfortably and cozily, or opt for the larger model if you want to sit sportily.

2. field of application

If you want to use the ball purely for free sitting or training, you can select the size according to the point. However, if you want to use your BOL for working in the office, the place of use is also an important decision criterion. For ball sizes 55 and 75 you should use a height-adjustable desk, otherwise you will not have a comfortable, ergonomic position, you will sit too high or too low. For standard desks with a height of approx. 72-76cm, you should always go for a VLUV 65, even if you are shorter or taller.

First, you should check that you have received the correct product ingredients.

1. to determine if you have received the correct fabric cover, please measure the diameter of the round top or bottom circle:
20-21 cm Ø: 65 cm BOL
25-26 cm Ø: 75 cm BOL

2. to determine if you have received the correct inner ball, please weigh it:
800-900 g: 55cm inner ball
1000-1100 g: 65 cms inner ball
1200-1300 g: 75 cms inner ball

The size of the inner ball is also printed near the valve.

If the inner ball is the right size, you can safely inflate it to the size of the outer shell. The material, a very flexible, burst-proof PVC, is extremely adaptable and can be inflated much larger without hesitation, but at least to the size of the ball shell. You need of course, as described, a good pump that can generate an appropriate pressure. This is included with the ball.

In the beginning, the inner ball can still be a little hard, especially in cold weather, but the material expands over the course of about 2 hours and becomes softer. Mostly you can also deflate some air after 24 hours after complete inflation and this also makes the ball softer.

A slight loss of air over a period of 6-12 months is normal, just pump a little with the enclosed hand pump. If your VLUV loses pressure faster, please check first:

1. room temperature stable? If the room temperature is reduced from approx. 2-3 degrees Celsius, the decreasing internal pressure may cause you to inflate the ball further.

2. sealing plug pressed in tightly? Please check whether the sealing plug has been pressed in firmly and flush.

If neither of the two points apply, please first replace the sealing plug with the replacement plug that came with the set and check whether the ball continues to lose air. If you still notice a pressure loss, please contact us via our contact form, we will of course help you immediately.

The fabric covers VLUV STOV, SOVA, VARM , VEGA,VLIP and LEIV are machine washable at 30 degrees. Just deflate and throw the cover in the wash. If there is only a small stain, you can also clean the entire ball, in the shower with soap and lukewarm water and then dry the ball / cushion in the sun or on the radiator. It won't get moldy, since the inner ball is a closed rubber ball.

The covers of the VEEL model can be carefully wiped with a damp cloth.

The covers of the VELT model can be carefully rinsed with cold water or dry cleaned.

Try to reduce the internal pressure of the ball by leaving it in a cooler room, e.g. cellar or garage, for about 3-4 hours. After that, the internal pressure should be reduced to the point where you can reach and open the cap.

The zipper does not close.

Normally, your BOL is already bulging before the zipper can no longer be closed. Please deflate a little and try closing the zipper again. Tip: press the inner ball in deeply with your thumb before the slider, this makes it easier to close.

We manufacture our BOL seat balls so that you achieve the most ideal seat height possible. On a BOL with 60-65cm you don't sit at 60-65cm high; depending on the air pressure and weight load, you sink about 10-15cm and thus achieve an acceptable seat height by increasing or decreasing the air pressure in the ball accordingly.

For warranty reasons, we always need to sell the entire product, so we do not offer the fabric cover/pillow case/cover on its own. This is because we can only guarantee the safety of the product when using our quality tested inner cushion.

An exception is if you already own our VLUV indoor ball. Just write us an email or contact us in chat.

The stand-up weight is a disc with a weight of about 800g which you put through the zipper of the cover and then push down to the bottom of the ball cover. The weight acts as a "stand-up". To install it, you need to deflate about 30% of the air from the inner cover, then insert the weight into the cover, and then pump the inner ball back up. The disc is then clamped against the outer shell by the air pressure and thus fixed.
