Heated Rear Seat Cover 12V-24V - Auto Shutoff, Fits Full Bench

Front seat heaters get all the attention, and the back bench stays cold the whole drive. This pad covers the full width of a standard 2nd-row seat, 126 by 47cm, so passengers in the back aren't stuck relying on the front vents to eventually reach them. It runs on 12V or 24V, which means it works in a standard car as well as larger trucks and vans that use a 24V electrical system.

A heating pad that runs unattended in a car needs a way to stop itself, and this one does. The control switch on the cord lets you choose low or high heat, or turn it off entirely, and the system automatically cuts power once the surface reaches around 140F (60C), then turns back on once it drops below about 86F (30C). That cycle repeats on its own, so the pad isn't just running at a fixed temperature with no upper limit. The plug itself uses a Bakelite housing specifically to resist heat buildup at the connection point, which is where a lot of cheap 12V accessories fail first.

• 🔌 12V-24V Compatible – works in standard cars and larger 24V vehicles
• 🌡️ Automatic Thermal Cutoff – shuts off near 140F (60°C), resumes below 86F (30°C), cycling automatically
• 🎚️ Low / Off / High Switch – inline control box on the power cord
• 🧵 Layered Construction – polyester knit fabric over a single thick copper heating wire, cushioned with 5mm pearl cotton, backed with non-slip non-woven fabric
• 📏 Full Bench Size – 126 x 47cm (49.5 x 18.5in), sized for a standard 2nd-row seat
• 🪢 Elastic Strap + Buckle Mount – secures around the headrest and tucks into the seat gap so it won't shift out of place while heating
• 📦 Foldable Storage – folds down small when not in use

Loop the elastic straps around the headrest posts and pull them snug to hold the top of the pad in place. Take the plastic buckle piece and press it into the gap between the seat back and the seat cushion, which anchors the bottom of the pad so it can't slide forward. Plug the 12V connector into your vehicle's power outlet, and use the switch on the cord to pick low or high heat.

• The automatic thermal cutoff is a normal part of operation. If the pad feels like it's cycling on and off, this is the safety function working as designed, not a malfunction.
• Do not use on unattended children without adult supervision, and check the seat periodically during use.
• Inspect the cord and plug periodically for wear. Discontinue use if the cord is damaged.

• 1 x Heated rear seat cover with 12V-24V power cord

Plenty of heated seat pads in this category list a temperature and stop there. This one specifies what happens at the top of that range: power cuts automatically at about 140F (60°C) and only resumes once the pad cools below about 86F (30°C). That's the difference between a heating pad with an upper limit and one that just keeps climbing.

• Comparable full-size heated rear pads with a stated auto-shutoff or UL listing run $30 to $53 in this category. We priced this at the upper end of that range because of the dual 12V-24V support, which most competitors don't offer.
• The Bakelite plug housing is a specific material choice made to resist heat at the connection point, not just a generic plastic shell.
• The elastic strap and seat-gap buckle mount are small details, but a heating pad that slides out of position defeats the point of having one.
