merino wool stroller insert Customizable product.

Our new arrival of the season and its grand entrance! Yes, it's a merino wool insert – wool that has captured the hearts of millions of parents worldwide. Children love it too, knowing their naps won't end with wet backs! The benefits of merino wool are plentiful, but we'll focus on its most important features:
- it is thermoactive - you can use it both in winter and summer (it warms in winter and cools in summer)
- is hygroscopic - it absorbs moisture wonderfully, a MUST HAVE FOR SUMMER TRIPS,
- it is durable, merino wool retains its properties for a long time despite washing,
- it is soft and pleasant to the touch - your little one will love it,
- has anti-perspirant properties, although it does not prevent sweating (sweating is a natural way of regulating the temperature of our bodies, we won't lie to you that anti-perspirant pads exist - they would have to secrete chemicals that block receptors in our skin)
- is double-sided – merino wool on one side, linen on the other,
- It should be washed by hand or in a washing machine on wool mode.
As befits Beztroska, our brilliant boiled wool is matched by our quality and precision craftsmanship. We can confidently boast that there's no other merino wool stroller liner on the market made this way. What's more, our liner is reversible – you can choose one of our top designs for the other side. We've also added our ingenious solution – a vertical belt slot system – so no parent will think less of us when installing the liner (believe us, installing the liner in this form is pure pleasure!)
And how do you like our proposal? We have a feeling it's going to be a hit! We're even more excited because our search for the perfect merino wool took us over a year. You know we either do something 100% or not at all. That's why we're now ready to present our merino wool collection. You're probably wondering: can I order a merino insert for my stroller model? There could only be one answer worthy of Beztroska: click here and order the insert for your model. And if someone whispers a question in your ear: what about the pillow? Can I also order a wool pillow? You know us..
COMPOSITION:
- first page - 100% merino wool with RWS certificate
- the other side - 100% cotton certified OEKO TEX standard 100 class 1
- Filling - Polish-made upholstery foam,
- cotton trim made in Poland.
Washing instructions:
- wash by hand or in a washing machine on wool mode.
- spin at low speed (important!)
- do not use bleach or softeners (do not wash in baby detergents containing bleaching agents, e.g. citric acid - we recommend wool detergent or baby shampoo).
- do not tumble dry,
- iron at 110 degrees.
There is no need to wash a merino wool product before first use. Merino wool is self-cleaning; if the product is not very dirty, simply air it out. We recommend hand washing at a maximum temperature of 30 degrees Celsius without soaking. Only use wool detergents or a gentle shampoo. If washing in a washing machine, select the wool cycle, a temperature of 20/30 degrees Celsius, and a low spin cycle. Machine wash at your own risk. The manufacturer is not responsible for improper operation of the washing machine or a malfunctioning wash cycle (Article 548 of the Civil Code). Pilling in merino wool is a natural phenomenon and results from shorter fibers emerging to the surface – it is not, in itself, a product defect. In the case of boiled wool, pilling is very limited, but may occur where, for example, shoes rub against the wool.
If you have any questions about our products, please call us between 10:00-16:00 +48 730-699-199
Each product is elegantly packaged and comes with a dedicated label, receipt or, upon request, VAT/personal invoice.
When you purchase from us, you receive a two-year warranty and official proof of purchase. Discover our program to extend the life of your worry-free products.
