You've tried cushions before. They all said they wouldn't flatten. They all did.
PlushCore is built differently. Here's how:

PlushCore's FloatZone™ dense gel construction is engineered specifically to prevent the pressure collapse that causes other cushions to fail. Unlike memory foam that compresses and stays compressed, our adaptive gel redistributes weight continuously across hundreds of support cells—meaning it won't bottom out even after months of daily use.

You're not paying for another cushion—you're investing in one that actually solves the problem. Most $20-$30 foam cushions flatten within a week, forcing you to buy replacements repeatedly. PlushCore is built with medical-grade gel technology that maintains support for years, making it the last cushion you'll need to buy.

Orders are usually fulfilled with USPS.

Depending on your location, your package will arrive at your doorstep within 5-9 days.

Our warehouse is located in the Bolingbrook, Illinois United States.

The Problem

The Truth About "Won't Flatten" Cushions

You've felt it before.

Week 1: Relief. You can finally sit without shifting every 10 minutes.

Week 2: The tailbone pressure is creeping back.

Week 3: You're sitting on a deflated pancake. The pain is back.

Here's why:

Cushions don't just flatten - they collapse unevenly under your weight. That forces pressure right back onto your tailbone and sciatic nerve.

Memory foam compresses and stays compressed. Gel spreads out. Even expensive honeycomb grids bottom out after months of real sitting.

You're stuck in the loop: $80 spent. Week 1 hope. Week 3 disappointment. Repeat.

You didn't pick the wrong cushion. Standard materials can't hold stable pressure.

What if one cushion could hold its support from Day 1 to Year 5?

The Solution

The Only Cushion Engineered To Never Bottom Out

PlushCore isn't just another gel cushion. It's engineered to fix everything traditional cushions get wrong.

✓ FloatZone™ Gel Core Our patented gel structure creates a pressure-free zone for your tailbone. Instead of compressing like foam or spreading like cheap gel, it continuously redistributes weight. Your tailbone literally floats.

✓ Pressure Collapse Prevention Can't be compressed, flattened, or crushed. Even after years of 8-hour days.

✓ Multi-Density Support Firm where you need stability, soft where you need relief. Traditional cushions are one density everywhere—which is why they fail.

✓ Temperature-Neutral Gel Stays cool in summer, doesn't harden in winter. No sweating through your chair or sitting on a frozen brick.

✓ 5+ Year Durability One cushion replaces dozens of disposable foam cushions. Customers report the same relief on Day 1,000 as Day 1.

✓ Universal Fit Design Works on office chairs, car seats, wheelchairs, dining chairs. Non-slip base locks it in place on any surface.

Traditional Cushions Fail At All Of These...

They flatten. Support collapses. Pain creeps back. You're buying replacements every few months.

PlushCore Succeeds At All Of Them.

Support holds for years. Pain stays gone. One purchase. Problem solved.

NO RISK PROMISE

Try PlushCore Risk-Free for 90 Days

Use PlushCore for a full 90 days. Sit on it for 8-hour workdays. Take it on road trips. Test it on every chair you own.

If you don't feel relief in the first week - if the support doesn't hold after months of use - if you're not sitting pain-free for the first time in years - we'll refund you.

No hoops. No hassles. No questions.

Just email us, send it back, and we'll process your refund immediately.

Why can we make this guarantee?

Because out of 11,000 orders, less than 1% have been returned.

We're not asking you to trust us. We're asking you to test it through real sitting time—8-hour workdays, long drives, months of daily use. If it flattens like the others, you get your money back.

You have nothing to lose except the pain that's been controlling your life.

Your Questions Answered...

You have 90 days to try PlushCore—not the typical 30-day window most companies offer. That's three full months to test it on long drives, full workdays, everywhere you sit. If it doesn't deliver lasting relief, return it for a full refund. We cover shipping both ways. No restocking fees, no hassle, no questions asked. We're confident PlushCore will work because it addresses the root problem (pressure collapse), but if it doesn't work for your specific situation, you risk nothing.

PlushCore works for sitting pain caused by pressure-related issues—which includes tailbone pain, sciatica, hip discomfort, and lower back strain. Here's how: The gel's coccyx cutout completely lifts your tailbone off the surface (eliminating direct pressure), while the honeycomb structure distributes weight evenly across your sit bones and thighs. This reduces nerve compression that causes sciatica and prevents the uneven pressure that strains your hips and back. That said, if your pain is from a condition that requires medical intervention (like a severe herniated disc), PlushCore provides relief but isn't a replacement for medical treatment.

PlushCore is built for years of daily use, not months. Our gel construction is the same material used in medical-grade wheelchair cushions designed for 24/7 use. We have customers who've been using the same PlushCore for 4+ years with no loss of support. Unlike foam that degrades from compression, gel is resilient—it bounces back to its original shape thousands of times. The washable cover can be replaced if needed, but the gel core itself maintains its integrity for years. We're so confident, we back it with our 90-day guarantee.

PlushCore has a non-slip rubber base that grips most chair surfaces—fabric, leather, mesh, even wood. Once you sit down, it stays in place. No sliding forward during meetings, no adjusting it every time you shift positions. For extra smooth surfaces (like some car seats), the included carry case has non-slip material you can place underneath. The cushion is also contoured to naturally cradle your body, which helps keep it positioned correctly without conscious effort on your part.

PlushCore measures 18" x 16" x 2.5"—designed to fit most standard office chairs, dining chairs, car seats, and wheelchairs. It's wide enough to support most body types (tested up to 300+ lbs) but not so large that it overhangs smaller chairs. The contoured design naturally centers itself under you. If you have an unusually wide or narrow chair, measure your seat width—PlushCore works best on seats 16-20 inches wide. For车seats specifically, it fits most sedans, SUVs, and trucks. If sizing doesn't work for your specific chair, you're covered by our 90-day return policy.

You'll feel the difference immediately—within the first few minutes of sitting. There's no break-in period because gel doesn't need to conform like foam does. The moment you sit down, the honeycomb cells distribute your weight and lift your tailbone. However, here's what many customers report: the first hour proves it won't collapse (unlike foam that feels good briefly), but the real "aha moment" comes around hour 2-3 when you realize you haven't shifted positions, haven't thought about pain, and don't dread standing up. That's when you know PlushCore is actually working—not just masking pain temporarily, but preventing the pressure buildup that causes it.

We offer free shipping on all orders. Your PlushCore comes with a 90-day relief guarantee—if you're not sitting pain-free and comfortable all day, return it for a full refund, no questions asked. Every cushion also includes a 2-year manufacturer's warranty against defects.
