Mattress topper
2–3 inches of memory foam transforms a stock bunk. Measure your bunk before ordering.

Sleep, explained.
Updated October 5, 2026
You spend a third of your life in the bunk. A stock sleeper mattress is a plywood board with fabric on it. Fixing your sleep setup is the highest-ROI comfort upgrade after the seat.
What to look for
Heated blanket (12V)
Runs off the truck's power. Warm bunk without idling — that's the whole game in winter.
Sleeping bag rating
A -30°C bag is overkill for most, but cheap insurance if the heater dies at 3 AM.
Common mistakes
- Buying a topper that doesn't fit the bunk — measure first.
- Running a 120V heated blanket off an inverter instead of getting a 12V one.
- Ignoring the pillow. Your neck will remind you.
Ranked picks

#1 — 12V heated blanket
A 12V heated blanket is the cheapest honest fix for a cold bunk. Our survival-essential pick.
15/20
#2 — Akozon 12V fleece travel throw
Digital temp control and a timer on a 12V throw. Set it, sleep, don't drain the batteries.
15/20
#3 — Linenspa 2″ Gel Memory Foam Mattress Topper — Twin XL
Two inches of gel memory foam, Twin XL for the bunk. Sleeps cooler than plain foam.
15/20
#4 — Yanes yukon −30°C (-22 °F) winter mummy sleeping bag
A minus-30 mummy bag for the nights the heater can't cover. Packs smaller than you'd think.
14/20

The overnight 12V blanket. Bigger coverage than the throw, same plug-in simplicity.
14/20
#6 — Foamma 5″ × 48″ × 75″ Firm Bunk Mattress — Truck/RV Sized
A firm bunk mattress in truck and RV sizing. For when a topper is a bandage and you need the real fix.
13/20
#7 — Browning discover −20°F sleeping bag
A 20-degree bag for three-season bunk duty. Not the deep-winter answer.
13/20

The budget 12V heated blanket. Warms the bunk; the thermostat is simpler than the top pick.
13/20
#9 — Zinus 8″ green tea memory foam mattress — twin
Eight inches of memory foam for the bunk. Thick, comfortable, and a pain to maneuver into the cab.
12/20
#10 — Derby XXL −30°C (-22 °F) heavy-duty sleeping bag
Roomy alternative. Space to turn over, which matters more than it sounds at 3 a.m.
12/20
#11 — LUCID 3″ Gel Memory Foam Mattress Topper — Twin XL (Ultra Plush)
Three inches of gel foam for the bunk. Thicker than the Linenspa, simpler build.

Sleep questions
What size topper fits a truck bunk?
Most bunks are twin or twin XL, but measure yours — they vary. A topper that's too big bunches up; too small leaves cold spots.
Will a 12V blanket drain my batteries?
They draw 4–5 amps. Overnight on a healthy battery bank is fine. Check our heated blanket runtime calculator.
