Description
Description
Long stretches at a desk or behind the wheel put steady pressure on the tailbone and leave the lower back with nothing to lean into. This two-piece set answers both at once. The seat cushion is moulded from memory foam with a coccyx cutout at the rear, so your weight is carried across the sit bones instead of the tailbone itself. The matching lumbar pad fills the hollow at the base of the spine that most chair backs leave wide open.
Memory foam softens with body heat and takes on the shape of whoever is sitting on it, then recovers between uses rather than flattening into a permanent dent. Both pieces are moulded to shape rather than simply stuffed, which is what keeps the profile consistent from the first week through to the hundredth. The set comes in black or blue, two colours that sit quietly in an office or a car interior without drawing attention to themselves.
Use the pair together on an office chair for long working days, split them between a desk chair and a car seat, or keep the lumbar pad in the car for the commute. This is comfort seating rather than a medical device, so if you have ongoing back discomfort please speak to a qualified professional instead of relying on a cushion alone. Nothing needs assembly. Unpack both pieces, set them in place, and shift them until the support lands where you want it.

Two Problems, One Set
Long stretches at a desk or behind the wheel put steady pressure on the tailbone and leave the lower back with nothing to lean into. This two piece set answers both at once.
Coccyx Cutout Takes The Pressure Off
The seat cushion is moulded with a cutout at the back so your tailbone sits over open space rather than carrying your weight against a hard chair.
For Long Days And Long Drives
Both pieces move easily between an office chair and a car seat, which is where the hours actually add up. The9thHour sells them together for that reason.

Frequently Asked Questions
What comes in the set?
A moulded memory foam seat cushion with a coccyx cutout, and a matching lumbar cushion for the back of the chair. They work together or separately.
What does the cutout actually do?
It removes the material directly under the tailbone, so your weight is carried by the surrounding area instead of pressing on the most sensitive point.
Will it fit a car seat?
Yes. Both pieces are sized for standard car seats as well as office chairs, and non slip backing keeps the seat cushion from sliding during a drive.
Will the foam flatten?
Memory foam recovers its shape between uses rather than compressing permanently, which is the main reason to choose it over a fibre filled cushion.
Are the covers washable?
Both covers unzip and go in the machine on a cool cycle, then air dry. The foam cores stay out of the wash.
