Adjustable leaf-spring prestressing changes bed base slat stiffness, giving simple hardness tuning for different body weights and comfort needs.

A hanging elastic insert in a slatted bed shoulder recess enables deeper sinking, lower pressure, and stable spinal alignment for side sleepers.

A suspended elastic insert in a slatted bed shoulder zone relieves joint pressure while preserving support and spinal alignment.

A rotatable stop with multiple contact zones lets a bed base suspension tune compression stroke and damping without a complex abutment.

Curved spring arms routed around female connectors even out mattress support and keep spring characteristics stable with adjustable comfort.

Segmented beam sections on bendable strips cut bed base weight, improve mattress airflow, and allow body-following support with varied damping.

A straight spring leg with V- or U-shaped bending avoids roll-packing hooking, cuts wire use, and keeps end rings secure in lacing wire.

A movable longitudinal carriage lets bearing bolts shift under load, increasing spring deflection, interactivity, and lying comfort.

Air-supported telescoping tubes with backup springs and washable segments improve patient support, hygiene, and bed uptime.

Actuated rigid-flex support elements reshape a bed surface to redistribute pressure, work with foam mattresses, and help prevent bedsores.

A sliding pulley-guided elastic support element simplifies slatted bed rests, reducing friction, wear, weight, and cost while improving spinal support.

Removable locking pins and pivoting L-shaped spacers let a box spring fold flat for lower shipping cost without costly hinge hardware.

Rigid molded bodies linked by elastic connectors create a seat that adapts to anatomy while cutting guide complexity, material use, and cleaning effort.

Arcuate slitted tension members flex in sofa mode and stiffen in bed mode to prevent sagging while preserving comfort.
