Built for the Gooseneck: The SleeperKing Western Serenity Series Horse Trailer Mattress — Copper Comfort

After a long day at the show, the rodeo, or the trailhead, you deserve real rest. The Western Serenity Series from Spring Air, 12 inches thick and made exclusively for SleeperKing, is built to your exact dimensions to fit the gooseneck bed or living quarters of your horse trailer. It's designed for comfort across all body types and sleeping styles — side, belly, and back sleepers.

Experience the Serenity Difference in Your Living Quarters:

  • ✦ Custom Fit to Your Trailer: Built to the width and length you provide, with rounded or angled corners available to match the nose of your gooseneck.
  • ✦ Quality Quilted Tops: Not stretched fabric. Real quilted construction built to handle the miles between events.
  • ✦ Designed for Everyone: Exceptional comfort for all body types and preferred sleeping positions.
  • ✦ Individualized Support: 1,000 Comfort Coils contour to your body, minimizing pressure points after a long day in the saddle.
  • ✦ Enhanced Lumbar Support: Our unique Copper Infused Lumbar Layer (the blue coils in the middle!) gives targeted support to a lower back that's been hauling, saddling, and mucking all day.
  • ✦ Stay Cool While You Sleep: Gel Enhanced Comfort Foam helps regulate body temperature on warm summer show weekends.
  • ✦ Cool and Inviting: A premium Cool to the Touch cover keeps the bed fresh in a closed-up trailer.
  • ✦ Easy to Maintain: Reinforced Handles make it easier to rotate and position in a tight gooseneck.
  • ✦ Fully Compliant: Meets MVSS302 flammability regulations for vehicle interiors.
  • ✦ Simple Setup: Ships roll-packed, easy to carry through a narrow LQ door.
How to Measure Your Trailer Bed
1. Measure the width and length of the bed platform at its widest points.
2. If the corners are rounded or angled to fit the gooseneck nose, measure how far each corner curves or cuts in.
3. Measure from the platform to the ceiling to make sure you'll have comfortable headroom.
4. Enter your measurements above. Not sure? Contact us before ordering and we'll help you get it right.

Frequently asked questions

Find answers to common questions about our products and services.

Yes. Every Western Serenity Series mattress is built to the exact width and length you enter on the product page, so it's made for your trailer rather than a "close enough" standard size. If your bed platform has rounded or angled corners to fit the gooseneck nose, select the corner style and enter the radius or cut size, and we'll build it to match.
Measure the width and length of the bed platform at its widest points. If the corners curve or angle in at the nose, measure how far each corner cuts in. Then measure from the platform to the ceiling to make sure a 12-inch mattress leaves you comfortable headroom. Not sure about your measurements? Contact us before ordering and we'll help you get it right.
It depends on your trailer's headroom. Most people want enough clearance to sit up in bed, so measure from the platform to the ceiling before ordering. If clearance is tight, reach out and we'll help you decide whether the Serenity is the right fit for your space.
Because each mattress is cut to your dimensions, custom-size orders are non-returnable. That's why we ask you to confirm your measurements before checkout, and why we're happy to review them with you before your order is placed.
Shipping is free to the continental USA. The mattress arrives roll-packed, which makes it easy to carry through a narrow LQ door and into the gooseneck before unrolling. Give it time to fully expand after unpacking.
