About Simplfill

From frustration to innovation

Every horse owner knows the struggle — trying to stuff hay into a floppy hay bag that just won’t stay open. It’s awkward, time-consuming, and messy.

That’s exactly the problem Gijs, the creator of Simplfill, faced when he started using rationed hay bags while living in Sweden.

One evening, sitting at the kitchen table with his children, he sketched an idea on a piece of paper — a simple insert that could hold a hay bag upright while being filled. A quick prototype made from cardboard proved the concept, and before long, the first Simplfill was born.

A simple idea that changed the routine

Simplfill is a foldable, rigid insert that transforms any hay bag or hay net into a stable, box-shaped container while you fill it.

You can throw hay in with both hands, fill the corners, even press it down — the bag won’t collapse.

When the bag is filled, simply pull Simplfill out through the open bottom. A quick tug keeps the hay neatly in place — ready to hang or tie. Then, move on to the next bag. It’s that easy.

Why it matters

What started as a small idea at the kitchen table has now grown into a tool trusted by riders, grooms, and stable owners across Europe.

Simplfill doesn’t just save time — it removes one of the daily annoyances of horse care.

With Simplfill, filling hay bags becomes:

• Quick and frustration-free

• Neat and mess-free

• Easier on your hands and your patience

• Perfect for both hay bags and hay nets

Built by horse people, for horse people

Simplfill was a finalist in the Swedish Equestrian Innovation Awards, a recognition of its clever yet practical design.

Our goal is simple: to make stable routines smoother, smarter, and a little bit easier — so you can spend less time wrestling with hay bags and more time doing what you love most — caring for your horses.
