Sunluway Jacuzzi J-300 Spa Pillow Inserts 4-Pack — OE-Fit Replacement for 2004–2018, Waterproof Ergonomic Support

Sunluway 4-pack oval pillow inserts and back mounts replace worn headrests in Jacuzzi J-300 series spas for a snug OE-fit and renewed neck support.

If your Jacuzzi J-300 series hot tub headrests are cracked, compressed, or missing, these Sunluway replacement pieces restore comfort and appearance without modification. Designed to match the original 2455-263 / 2472-824 dimensions and mounting points, the set includes four inserts that snap into existing back mounts to recreate the original ergonomic contour and keep your spa looking and feeling like new.

Will these pillow inserts fit my J-300 model?

Yes — the Sunluway oval insert and back mount set is built to OE specifications for J-300 series hot tubs made between 2004 and 2018. They are intended as direct replacements for the common Jacuzzi part numbers listed by the manufacturer.

• Compatible models: J-310 through J-385 (J-300 series, 2004–2018).
• Replaces part numbers 2455-263, 2472-824, 2455-104, 2455-105.
• Designed to align with factory mounting tabs and recesses for a straightforward swap.

How comfortable and durable are these spa pillows?

Sunluway pillows combine an ergonomic shape with durable materials to support the head and neck during soaking. The polyurethane and rubber construction resists heat, moisture, and common spa chemicals to maintain shape and function over time.

• Ergonomic oval profile to cradle the neck and head comfortably.
• Waterproof and corrosion-resistant materials for long-term use.
• Firm but forgiving density keeps support without collapsing.

What is involved in installing the replacement inserts?

Installation is quick and typically requires no tools: remove the old insert and press the new Sunluway piece into the existing back mount until it locks. If your old back mounts are damaged, the set includes back-mount pieces to restore the mounting surface too.

• Simple push-fit design snaps into place in seconds.
• Back mounts match OE mounting geometry for proper alignment.
• No adhesives or drilling required for standard replacements.

How do these replacements change the look and maintenance of my spa?

Replacing worn headrests refreshes the spa’s visual appeal and makes routine cleaning easier. New inserts eliminate torn surfaces that trap dirt and chemicals, while the low-porosity material wipes clean and withstands regular water treatment cycles.

• Restores clean lines and uniform color to headrest areas.
• Non-porous surface reduces grime buildup for simple maintenance.
• Extends the usable life of your existing headrest assemblies.

Who is this for: This 4-pack from Sunluway is aimed at Jacuzzi J-300 owners, spa maintenance professionals, or hot tub refurbishers who need an OE-fit, durable headrest solution. It’s especially useful if you have multiple worn pillows to replace at once, want to improve bath-time comfort, or need parts that match factory mounting points for an easy, tool-free swap.
