There are two main criteria to consider:

1. body size
2. the scope

1. height

We offer 3 BOL sitting ball sizes for the following heights:

BOL 55: approx. 130–155 cm
BOL 65: approx. 155–180 cm
BOL 75: approx. 180–200 cm

Here you can choose the ball size that generally fits your height. Tip: Especially in the border areas between two ball sizes, i.e. approx. 152-157 cm and 178-182 cm, it is better to choose the smaller size if you want to sit comfortably and cozy, or opt for the larger model if you want to sit sporty .

2. scope of application

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

A high-quality double-acting hand pump is supplied with each BOL. However, you can also connect a bicycle pump.

First you have to check whether you have received the right product.

1. To determine whether you have received the correct outer cover, measure the diameter of the round top or bottom:
20-21 cm Ø: 65 cm BOL
25-26 cm Ø: 75 cm BOL

2. To determine whether you have received the correct bladder, you must weigh it:
800-900g: 55cm bladder
1000–1100 g: 65 cm bladder
1200–1300 g: 75 cm bladder

The size of the bladder is also indicated on the printing on the valve of most bladders.

If the inner bladder is the correct size, you can safely inflate it to the size of the outer cover. The material, a very supple, anti-burst PVC, is extremely flexible and can be inflated much larger without hesitation, but at least to the size of the ball's shell. Of course, as described, you need a good pump that can generate the right pressure. This is included with the ball.

The bladder may be a little stiff at first, especially in cold weather, but the material will expand and soften over the course of about 2 hours. After 24 hours, you can usually deflate the ball, which also softens it.

Take your time, it may take a few minutes. For a BOL 65 you need about 6 minutes, for a BOL 75 about 10 minutes. We advise you to inflate your BOL in stages, without haste and stress.

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

1. Room temperature stable? If the room temperature drops by approx. 2-3 degrees Celsius, the falling internal pressure may mean that you have to inflate the ball further.

2. Sealing plug pushed in properly? Check whether the sealing plug is pressed in properly and flat.

If neither applies, first replace the blanking plug with the replacement plug supplied with the kit and verify that the BOL continues to lose air. If you still notice a loss of pressure, please contact us via our Contact form , We will of course assist you immediately.

The fabric includes VLUV STOV , SOVA , VARM , VEGA, VLIP and LEIV can be machine washed at 30 degrees without any problem. To do this, deflate and wash the cover. If only a small stain needs to be removed, you can also clean the entire ball, for example in the shower, with soap and lukewarm water and then wash the ball / You can dry the ball in the sun or on the heating. Nothing can mold because the inner ball is a closed rubber ball.

The cover of the VEEL model can be gently rubbed off with a damp cloth.

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

Yes, using a VLUV sitting ball can be relaxing and soothing during and after pregnancy. However, we always recommend that you sit down carefully and, if possible, have someone else help you during the last weeks of pregnancy to avoid accidents.

Because of the warranty, we always have to sell the complete product. We can only guarantee the safety of the product if our quality-tested bladder is used.

Try to reduce the internal pressure of the ball by leaving it in a cooler area, such as a basement or garage, for about 3-4 hours. Thereafter, the internal pressure must be sufficiently reduced to reach and open the sealing plug.

The zipper does not close.

Normally your BOL is already filled before the zipper does not close. Deflate a little and try to close the zipper again. Tip: press the inner ball deeply with your thumb in front of the slider, then it closes more easily.

We make our BOL sitting balls in such a way that you reach the ideal sitting height. Of course you are not high on a BOL with 60-65cm. Depending on the air pressure and weight load, you will sink about 10-15cm and thus reach an acceptable seat height by increasing or decreasing the air pressure in the ball as desired.

The 36cm wide PIL&PED seat cushion is more suitable for narrow stools and benches and is more recommended for people with narrower hips. For office chairs, free sitting, more comfort and a wider hip width, we recommend the 40cm wide PIL&PED.

We only use high quality furniture fabrics. However, the fabrics vary in density, composition and weave, leading to different prices for the products.

The fabric includes VLUV STOV , SOVA , VARM and LEIV The cover can be machine washed at 30 degrees without hesitation. Simply open the zipper and remove the cover.

The UPP bottom weight is suitable for all 60-65cm BOL sitting balls.

The bottom weight is a disc weighing about 800 grams that you put through the zipper of the cover and then slide down to the bottom of the ball cover. To install it, you need to let out about 30% of the air from the bladder, then put the weight in the cover and then inflate the bladder again. The disc is then clamped against the outer cover by the air pressure and thus fixed.
