WHY KORDENA?
Why Kordena?
We only make one product — and we obsessed over getting it right.
While cheap seat cushions flatten within weeks, Kordena's memory foam is built to hold its shape through months of daily use. We tested for one thing: does it still feel supportive on day 100, not just day 1.
- Focused, not scattered — we don't sell fifty products. We perfected one.
- Real memory foam — dense, slow-rebound core, not the cheap filler foam that packs flat in weeks
- 30-day guarantee — if it doesn't work for you, we make it right
- Fast, tracked shipping — no wondering where your order is

Frequently asked questions
Does it fit my chair?
Yes. Kordena's 44x 44 x 14 cm design works on office chairs, car seats, gaming chairs, dining chairs, and wheelchairs. If it has a flat seat, it fits.
Is the cover washable?
Yes, the cover is removable and machine washable on a cold, gentle cycle. Air dry — don't tumble dry the foam insert.
Will it lose its shape over time?
No. Kordena uses slow-rebound memory foam, which holds its shape far longer than the compressed filler foam used in cheaper cushions. It won't flatten out after a few weeks.
What if it's not right for me?
You're covered by our 30-day money-back guarantee. If Kordena isn't the right fit, reach out and we'll make it right.
