Is there a sofa bed that combines a comfortable mattress, secure support without straps, and a cozy sofa design?

For instance, contemporary furniture brands like Koala, Brosa and Freedom offer sofa beds that do not rely on straps or cumbersome mechanisms for support.

These sofa beds typically feature simple pull-out systems or fold-down systems, with mattresses that balance occasional sleeping comfort with everyday seating functionality. Such designs also emphasize aesthetics, ensuring the sofa bed looks and feels inviting whether used for seating or sleeping.
