Frequently Asked Questions

Does it actually make a difference on a hard chair? +

Yes. The memory foam distributes seated weight across the full surface instead of concentrating it at a few points. The difference between sitting on a hard chair with and without the cushion is noticeable immediately.

Does it fit a standard office chair? +

Yes. The 45 x 45 cm square profile is sized to fit most standard office chairs, desk chairs, and task chairs without hanging over the edges.

Does it slide off the chair? +

The flat profile sits flush on standard seat surfaces. On smooth or angled seats, positioning the cushion toward the backrest helps keep it in place.

Does the foam go flat over time? +

No. The memory foam returns to its original shape after every use. It does not bottom out or lose density through regular daily sitting.

Can it be used in a car? +

Yes. The 45 x 45 cm dimensions fit most car seats. Keep one in the car for commutes and long drives.

Is the cover removable? +

The cover is not designed for removal. Spot clean with a damp cloth and air dry.

What colours are available? +

Blue, Yellow, White, Purple, Pink, Black, and Green.

How long does shipping typically take? +

Orders are processed within 1–2 business days, and delivery typically arrives in 7–10 business days. Tracking information is provided once your order ships so you can follow its progress every step of the way.
