Bedbinder vs IKEA SIGGERUD: which one actually works?
Two products that claim to fix the mattress gap. But they work in completely different ways. Here is the honest comparison.

The IKEA SIGGERUD is a foam wedge. It is a strip of foam that you push into the crack between two mattresses. It fills the gap from above. It costs around 10 euros and is available at IKEA stores.
The Bedbinder Deluxe is a horizontal mattress connector. It wraps around both mattresses underneath and pulls them tightly together. The gap cannot form because the mattresses are physically connected. It costs 49.95 euros.
They look like they solve the same problem. But one fills the gap temporarily. The other eliminates it permanently.

The SIGGERUD is cheap and easy to find. But it has the same problems as every foam wedge:
The SIGGERUD is a gap filler. It fills the symptom but ignores the cause. The mattresses are still two separate pieces that can move freely. That is why the gap keeps coming back.
The Bedbinder takes a fundamentally different approach. Instead of filling the gap, it prevents the gap from ever forming.
The Bedbinder is the original horizontal bed bridge. Over 15,000 couples use it every night. It has a 4.8-star rating and a 30-day satisfaction guarantee.
The IKEA SIGGERUD is fine if you need a quick, temporary fix for a one-time situation. A guest room, a holiday rental, or a short stay.
But if you sleep on two mattresses every night and want a real solution, the Bedbinder Deluxe is the clear winner. It costs more upfront but saves money in the long run. And it actually solves the problem instead of masking it.
No. The SIGGERUD is a foam wedge that sits in the gap. The Bedbinder is a horizontal mattress connector that wraps around both mattresses and pulls them together. They work in completely different ways.
No. The SIGGERUD only fills the gap. It does not connect the mattresses, so they can still slide apart. The Bedbinder physically connects both mattresses so they cannot move apart.
The Bedbinder is the better long-term solution. It eliminates the gap permanently and stops mattress sliding. The SIGGERUD is a budget option that fills the gap temporarily but needs replacing and does not prevent sliding.
The Bedbinder Deluxe eliminates the mattress gap permanently. Try it for 30 days. If it does not work, you get a full refund.
