Jan has exceeded my expectations in mentoring! I would especially like to emphasize Jan's incredible commitment and professionalism: I noticed at all times that he wanted to help me from the bottom of his heart! Jan was always very empathetic to my complex situation and gave me extremely valuable impulses that gave me more clarity and a completely new perspective. Jan is THE mentor who really pushes you into action and to your limits, so that you REALLY take a step forward instead of losing yourself in thought loops! I really appreciated the close mentoring, especially the frequent communication via Whatsapp voice messages and the 1:1 conversations.
I can really recommend Jan from the bottom of my heart!

Top advice! Jan has brought us professionally and at the same time so casually entertaining Samina closer and answered every little lay question without getting tired! Thanks for the perseverance! The purchase was totally worth it!
Since we have Samina, we are incredibly looking forward to falling asleep every evening comfortably and as if on a cloud - and my back pain is also gone! Thank you!

Jan Herzog is THE expert when it comes to the complex topic of sleep and regeneration. He puts his heart and soul into it and is the perfect mix of competence and sympathy. His friendly manner and empathy gave us a good feeling right from the start in our decision process to switch to Samina. The sleep system itself then completely convinced us: It is not cheap but absolutely worth its price due to the fact that good sleep is an elementary building block for health and well-being. Our sleep has improved significantly as a result! Our son has (almost) always slept through the night since the changeover. Great recommendation!

Passionate about it, very friendly and competent. The sleep system has its price, of course, but it seems to work. Long-term effects we can not yet judge, but so far we are satisfied!

Jan approached me in our get-to-know-you conversation with such trust as I have never experienced before. His questions and explanations were so understandable and friendly that we immediately exchanged ideas on a friendly level. I would never have thought how extensive the subject of sleep can be.
The Samina sleep world just "feels" right. We only notice the big difference again when we have slept away from home! It was absolutely the only right decision. We are absolutely happy with Jan's all around carefree package and will never try anything else!
Thank you Jan!!!

Jan Herzog is for me a very competent experienced expert with very sound knowledge.
He immediately recognized / understood my sleep problem and gave me the best advice.
I also particularly liked his very polite, friendly and empathetic manner.

From the very first night in my new sleeping system (I call it sleep comfort), neither my arms
neither my arms fell asleep nor did my neck/shoulder area hurt.
The slatted frame supports every sleeping position, so that I get up easily and relaxed in the morning.
The natural products of the system, let me sleep more climatized (less sweating).
The relaxed sleep through rewards me during the day with much more energy!

Thank you Jan Herzog
Special thanks to all who are involved in the development of the Samina sleep system

Sincerely
"Samina" for Sabina

Am very satisfied with the cushion. Fits perfectly for me. After realizing that the summer blanket fits me better for winter and the summer night dream blanket fits me better for summer or the fall/spring blanket is too hot for me, we agreed that I can exchange these blankets for each other. The still packed autumn / spring blanket I sent back and look forward to the summer night dream blanket. The advice was very competent and sympathetic. Kind regards Thomas Polzer

I am 100% convinced of the SAMINA sleep system. Since I have been sleeping in SAMINA, I have never slept more refreshed and better anywhere than at home. I no longer have back pain and feel that my sleep since then has been qualitatively much better and more regenerative than before. Absolutely recommend!

The Samina sleep system has exceeded my expectations. You can feel and smell the high quality of the bed system's materials. I was especially pleased that as a strong allergy sufferer I have no problems at all with the sheep's wool and do not get any allergic symptoms. My sleep has improved as a result and I am happy to lie down in my cozy bed in the evening.

I have come to know Jan Herzog as a friendly, warm-hearted and competent person who cares not only about sales and profit, but also about the person behind it. Before he even earned anything from me, he took a lot of time to share with me a wealth of tips and advice on how to improve my lifestyle and health. Thanks again for that Jan, because it is not only the bed system that is important, but also the topics like chronobiology, meditation and exercise. Therefore, I can recommend Jan Herzog as a coach or consultant to anyone who wants to take their health to the next level.
