Product description

High-density memory foam moulds to your hips, thighs and lower back at once, so the weight that normally lands on your tailbone spreads across the whole seat. The U-shaped rear cutout leaves the coccyx floating free, while the moulded backrest fills the hollow your car seat leaves behind your lumbar curve.
A central air channel and a brushed sweatshirt-knit cover pull heat away, so hour six feels like hour one. The rubberised base keeps it planted through corners and getting in and out. One piece - seat and back together - and it works just as well on an office chair as it does in the car.

Material & dimensions
Approx. 44 × 42 × 32 cm (17.3 × 16.5 × 12.6 in). Core: high-density memory foam moulded as one seat-and-backrest piece, with a U-shaped coccyx cutout and a central air channel. Cover: brushed sweatshirt-knit, removable and machine-washable. Base: rubberised non-slip backing. Available in Black, Dark Grey and Light Grey.
Care instructions
The cushion ships vacuum-compressed to protect it in transit - give it 24-48 hours out of the packaging to reach full height. Wash the cover separately at 30 °C and air-dry it. Never machine-wash or soak the foam core; spot-clean it with a damp cloth instead.
Shipping & returns
Delivery takes 3-7 business days, depending on your location. You'll receive a tracking link by email as soon as your order ships. Not satisfied? Contact us at info@autoboosty.com and we'll review your case as soon as possible!

This is a system, not a pillow.

Most car cushions are a single flat pad. This one is moulded as a single body - a contoured seat base and a full backrest - so the geometry stays exactly where it was designed to be, every time you get in.

🦴

Neck-to-tailbone alignment

The contoured backrest holds your lower spine in its natural curve, so you step out of the car standing straight instead of unfolding.

📐

Shaped to a pelvis, not a rectangle

A coccyx cutout and thigh shelves decide where the load lands. A flat pad only raises you - it doesn't move the pressure anywhere.

🧬

Adaptive memory foam

High-density foam conforms to your shape and rebounds after every drive - it won't flatten into a pancake after a month.

Eight hours seated. Still comfortable.

  • 1

    🦴 Tailbone stays free

    The U-shaped rear cutout removes contact entirely, so the ache that usually starts around hour two never arrives.

  • 2

    🪑 Your lower back gets something to lean on

    The moulded backrest fills the hollow most car seats leave, so you stop holding yourself upright with your own muscles.

  • 3

    🌬️ Heat has somewhere to go

    A channel down the middle and a brushed knit face move air instead of trapping it against you.

  • 4

    🔁 It springs back

    High-density foam returns to shape overnight instead of flattening into a pancake after a month.

The questions everyone asks

"Will it fit my car seat?" YES.

At 44 cm across it sits inside almost every bucket seat, including sports seats with raised bolsters. It rests on the seat rather than strapping to it, so there is nothing to mount.

"Will it push me too high?" NO.

The seat section is contoured, not a thick block - it lifts your hips slightly while dropping the tailbone into the cutout, so your eye line barely moves.

"Does it work with the headrest and seatbelt?" YES.

The backrest stops at the shoulder blades, so it never fights the headrest, and the belt runs across you exactly as it normally does.

"Will it flatten out after a few months?" NO.

High-density memory foam recovers overnight. If yours stops returning to shape, that's covered by the money-back guarantee.

FIND YOUR FIX

Where does it hurt?

Pick the spot that gives up first on a long drive. We will show you what fixes exactly that.

Neck & shoulders

Your head tips forward, and by the second hour the ache has settled between your shoulders.

Neck and lower back

Both ends give out. The headrest sits too flat and the seat leaves a hollow behind your lumbar curve.

Tailbone and lower back

You start shifting your weight around hour two and never quite get comfortable again.
