What Is SITTIVA Core™?
What Is SITTIVA Core™?

✓ Redistributes pressure more evenly
✓ Supports a stable sitting position
✓ Helps reduce constant shifting and squirming
✓ Breathable honeycomb design keeps you cooler
✓ Flexible gel rebounds instead of staying flattened
Built for desks, driving, gaming, dining chairs, wheelchairs, and anywhere you sit for hours at a time.
How Does It Work?
How Does It Work?
SITTIVA Core™ uses a flexible honeycomb gel grid that bends and rebounds under pressure instead of simply compressing like foam.
As you sit, the grid helps spread your weight across a wider area so less pressure is concentrated beneath your hips and tailbone.
✓ Flexes under pressure instead of bottoming out
✓ Spreads weight more evenly across the seat
✓ Helps reduce pressure hotspots
✓ Open cells allow heat and moisture to escape
✓ Rebounds when you move or stand up
The result is a cooler, more balanced sitting surface that stays comfortable for longer.

SITTIVA Core™
Your Seat Is Working Against You.
Most chairs concentrate pressure under your hips and tailbone — so you shift, slump, and tense up just to stay comfortable.
SITTIVA Core™ spreads that pressure across a flexible honeycomb grid, giving your pelvis a more stable foundation and your lower back less work to do.
Less pressure. Less shifting. Less strain.
Most Chairs Punish Your Body Within 30 Minutes
Your hips tilt, your tailbone takes the pressure, and your lower back starts working harder just to keep you upright. That’s why long workdays, drives, and study sessions leave you sore, stiff, and constantly shifting.
SITTIVA Core™ works differently. Its flexible honeycomb grid spreads your weight more evenly, helps reduce concentrated pressure beneath your hips and tailbone, and gives your pelvis a more stable foundation for longer sitting.
Less tailbone pressure. Better pelvic support. Less strain on your lower back.
The SITTIVA Difference
Most cushions move the problem around. The 100% Gel Seat Cushion eliminates it — from the very first sit.

Our Guaranteed Difference
We tried cushion after cushion and almost gave up — foam flattened, heat built up, and nothing stayed comfortable. Then we found the honeycomb gel design behind SITTIVA Core™.
