Premium Stand Up Liner Black for Hardside Waterbed Mattress

I'd forgot id ordered this. ButI remember it did work well.

I used this product to replace my old liner in my waterbed. Well made product, fits great, very strong. Also bought conditioner for bed.

It works fine!

I don’t usually write long reviews, but this one deserves it because I am genuinely frustrated. I ordered what was clearly listed as a King-size InnoMax Premium Stand-Up Waterbed Safety Liner, and what arrived was absolutely not a king. It was a queen, maybe even smaller. For something as specific and expensive as a waterbed liner, that kind of mistake is inexcusable. First off, when you’re dealing with a waterbed, size matters — it’s not something you can just “make work.” A liner that doesn’t fit properly is completely useless, not to mention unsafe. It defeats the entire purpose of having a safety liner. The fit was off by several inches all around, which means water could easily spill or leak over the sides. It’s a design meant to protect, but how can it if it doesn’t even match the mattress dimensions? The listing made it sound “premium,” with a price tag to match, but there was absolutely nothing premium about this experience. The material was average at best — thin, wrinkled straight out of the box, and didn’t give me confidence it would hold up over time. For something marketed as durable and heavy-duty, it looked and felt more like bargain-bin vinyl. And the worst part? No returns. I tried to initiate a return as soon as I noticed the sizing issue, and the policy blocked it. For the cost, this is unacceptable. If you can’t stand behind your product or fix mistakes when they happen, you shouldn’t be calling it “premium.” So now I’m stuck with a completely wrong-sized liner, out the money, and with zero recourse. Between the misleading description, the incorrect sizing, and the lack of customer support, this has been one of the most disappointing purchases I’ve made on Amazon in years. Save your time, your money, and your patience — there are better options out there. This one’s a hard pass. #AmazonFinds #RealReview #ConsumerAlert #HomeEssentials #LuxuryLifestyle #DobermanMom

Used for a 46 year old waterbed we have had since married. Replaced liner, mattress and heater. Hope we get another 46 years out of them!
