If you've got a Jacuzzi J-400 series hot tub from mid-2009 or later and your headrest pillow is looking worse for wear, this is exactly what you need! This genuine Jacuzzi replacement pillow fits perfectly into those J-400 models, giving you that comfortable head support while you're relaxing in the bubbles. Now, quick heads up - this is just the pillow itself, so you'll need to reuse the fastening clips from your old pillow to attach it. But if your clips are still in good shape, this replacement will have your hot tub looking and feeling fresh again. Perfect for when the original pillow has gotten faded, cracked, or just doesn't provide that comfortable support anymore. It's one of those simple maintenance items that makes a big difference in your hot tub experience. Nothing worse than a worn-out pillow when you're trying to relax, right? This gets you back to comfortable soaking in no time!
