What's Included
Why Customers Buy the Set
Most people buy the seat cushion first — then come back for the back cushion within 30 days. This bundle gives you both from day one at 29% off.
The seat cushion's U-shaped coccyx cutout suspends your tailbone so it never presses against a hard surface. The contoured back cushion supports your natural lumbar curve to keep your spine aligned. Together, they eliminate the two most common causes of sitting pain: tailbone pressure and lower back strain.
How It Works
The U-shaped cutout suspends your coccyx in open space — no more compression on the most sensitive bone in your body.
Contoured lumbar support promotes natural pelvic tilt and proper posture. Adjustable straps secure it to any chair.
Heat-responsive memory foam molds to your body within minutes. Use at your desk, in your car, or anywhere you sit.
What Customers Are Saying
"Bought the set for my home office. The difference from day one was incredible — no more lower back stiffness by 2pm. Should have done this years ago instead of wasting money on expensive chairs."
Mark T. Verified Buyer"I have sciatica and this combo changed my life. The seat cushion takes pressure off my tailbone and the back cushion keeps me from slouching. I bought a second set for my car."
Diana L. Verified Buyer"Got this for my husband who drives 3+ hours a day. He says the back pain he used to come home with is basically gone. We're getting one for my desk next."

Common Questions
Will this fit my chair?
Yes. Both cushions are designed with a universal fit for office chairs, car seats, wheelchairs, airplane seats, dining chairs, and gaming chairs. The seat cushion has a non-slip rubber base, and the back cushion has adjustable straps.
Will they go flat over time?
No. The heat-responsive memory foam retains its shape and density. Thousands of customers confirm they hold up after 1+ years of daily use. And if anything ever happens — lifetime replacement guarantee.
Do they help with sciatica?
The seat cushion's U-shaped coccyx cutout was specifically designed to relieve pressure on the sciatic nerve. Combined with the lumbar support from the back cushion, this set addresses both the pressure point and the spinal alignment issues that contribute to sciatic pain.
Are the covers machine washable?
Yes — both covers unzip and are fully machine washable. Gentle cycle, air dry or tumble dry low.
What if it doesn't work for me?
Try the set for 30 days. If you don't feel a meaningful difference, return it for a full refund. No restocking fees, no hassle. Beyond that, both cushions are covered by our lifetime replacement guarantee.
Is the bundle HSA/FSA eligible?
Yes. Both the seat cushion and back cushion qualify as HSA/FSA eligible purchases. You can use your pre-tax health savings for the entire bundle.

Frequently asked questions
Everlasting Comfort designs ergonomic comfort products that are built to last and backed by real testing. Our memory foam is CertiPUR-US certified for content, emissions, and durability, and our covers are OEKO-TEX certified, meaning they're tested free of harmful substances. Many of our supports are contoured with input from physical therapists and have earned "Doctor Recommended" positioning, so you're getting comfort that's engineered rather than guesswork.
Our cushions and supports are ergonomically designed to promote healthy posture and help relieve pressure during everyday sitting, sleeping, and travel. Many customers use them to stay more comfortable at a desk, in the car, or in bed. That said, our products are comfort aids and not a substitute for medical treatment, so if you have a specific health condition we recommend checking with your doctor about what's right for you.
Yes — we offer free shipping on every order, with no minimum required. Orders ship from our U.S. warehouse and you'll receive tracking so you can follow your package to your door. Most orders are processed within one to two business days, and delivery times vary by your location once the order is on its way.
We stand behind everything we make with a lifetime replacement-or-money-back guarantee. If a product breaks, malfunctions, or simply doesn't work out for you, reach out and we'll make it right with a free replacement or a full refund. In most cases you won't even need to ship the item back — just contact our support team with your order details and proof of purchase.
Our non-electronic products carry a lifetime warranty against defects in materials and workmanship, so you're covered for the long haul. Electronic products, such as humidifiers and diffusers, are covered by a 2-year warranty. If anything ever falls short, our support team will help you sort out a replacement or refund.
Many of our seat cushions and support products qualify as HSA/FSA eligible, which means you may be able to purchase them using pre-tax health spending funds. Eligibility can depend on your specific plan and how your provider classifies the item, so we recommend confirming with your HSA/FSA administrator before purchase. Keep your receipt as proof of purchase for reimbursement.
Care is simple and depends on the item. Products with removable covers are designed for easy cleaning — most covers can be unzipped and machine washed, while the memory foam core should be spot cleaned and air dried rather than submerged. For fabric items like blankets, follow the care label, and for electronics like humidifiers, wipe down and rinse the tank regularly to keep them running fresh. Always check the label on your specific product for exact instructions.
Yes. Our memory foam is CertiPUR-US certified, meaning it's independently tested to be made without ozone depleters, certain flame retardants, heavy metals, formaldehyde, and other substances of concern, with low VOC emissions for indoor air quality. Our covers are OEKO-TEX certified as well. You can rest easy knowing our materials are made with your health and home in mind.
Our products are built for the long term. We use high-density memory foam engineered to hold its shape and support for years of daily use rather than flattening out quickly. Combined with our lifetime warranty on non-electronics, you can count on lasting comfort — and if anything ever goes wrong, we've got you covered.
Our friendly U.S.-based support team is here to help. You can reach us by phone at (737) 270-7661, Monday through Friday, 9am–5pm CST, or by email through our support address for order questions, guarantee claims, and product help. We aim to respond quickly and make every issue easy to resolve.
