Description

The Ergonomic Memory Foam Seat Cushion cradles your hips and tailbone in a supportive U shaped cutout, so pressure never builds up the way it does on a flat, hard seat.

High density memory foam holds its shape through a full day of sitting, while the breathable mesh cover and non slip base keep you comfortable whether you're at a desk chair, a dining chair, or in the car.

Ideal for: office chairs, home offices, study spaces, and everyday seating.

Material: high density memory foam with a breathable mesh cover.

Dimensions: 41cm x 37cm (16.14in x 14.57in).

How to use
Set the cushion on your chair with the cut-out notch facing the back edge, so your tailbone rests in the open space rather than on the foam. Sit with your hips pushed back toward the notch and your weight even across both sit bones. It works on desk chairs, dining chairs, or car seats — just use the elastic strap underneath to keep it from sliding when you stand up and sit back down.
Shipping process

Free shipping on all orders over $100. Orders typically arrive within 5–8 business days with tracking, and every order is backed by 30-day returns.

Why Nookly

The difference you feel by the end of the day

Thoughtful Design

Shaped from real posture data, not guesswork - so support lands exactly where your body needs it.

Premium Materials

High-density memory foam with breathable mesh cover - chosen to last, not to cut costs.

Workspace Wellness

Built to make the hours you spend seated feel a little kinder to your body.

Built for Everyday

Light enough to move between chairs, quiet enough to forget it's even there.

Where It Supports You

Designed around the way you actually sit

  • 1

    Tailbone

    The U-shaped cut-out lifts pressure off your tailbone so it never touches a hard surface.

  • 2

    Hips & sit bones

    Contoured memory foam cradles both sides evenly so weight doesn't pool on one hip.

  • 3

    Lower back

    An even seated base keeps your pelvis level, which takes strain off your lower back.

  • 4

    Thighs

    The tapered front edge avoids pressing into the backs of your thighs, so circulation stays easy.

The Nookly Method

Three steps to a better seat

Place 01

Place

Set the cushion on your chair with the notch toward the back edge.

Settle in 02

Settle in

Sit back so your tailbone rests in the open notch, not on the foam.

Sit through it 03

Sit through it

Work through your day as usual — the foam adjusts to you, not the other way around.

Good to Know

Questions, answered

Will this fit my office chair?
Yes — the cushion is 17in x 15in x 3in and works on most desk chairs, dining chairs, and car seats. The elastic strap underneath keeps it in place on chairs with or without a solid seat base.
How firm is the foam?
It's high-density memory foam, firmer than a decorative pillow but designed to slowly contour to your shape rather than flatten. Most people notice it softening slightly to their sit bones within the first week.
How do I clean it?
Remove the mesh cover and hand wash it in cold water, then air dry. The foam core itself should only be spot-cleaned and never fully submerged.
What if it doesn't help my tailbone pain?
Every cushion is backed by our 30-day return window, so you can try it through a couple of full workweeks and send it back for a full refund if it isn't a fit.
Is the notch cut-out really necessary?
Yes — the U-shaped notch is what takes pressure off your tailbone specifically. Sitting with the notch facing forward instead of back reduces the benefit, so line it up with the back edge of the seat.
