🛒 Buyer’s Guide: What to Look for in a Coleman 17B/17R Mattress

Here are the top things to keep in mind while shopping:

✔️ Size & Fit

• Measure your space first!

• Look for “Short Queen” or “RV Queen” (60" x 74"/75")

• For bunks, 28" x 72" is typical

✔️ Mattress Thickness

• 6"–8" is standard for RVs

• Thicker = comfier, but make sure you can still open cabinets or windows

✔️ Foam vs. Hybrid

• Memory Foam: Best for contouring, motion isolation

• Hybrid: Combines foam and coils for bounce and durability

✔️ Temperature Control

• Look for gel-infused or open-cell foams to help stay cool in summer

✔️ Weight

• Keep in mind the total weight of the mattress, especially for bunk areas where heavy mattresses could sag over time

✔️ Certifications

• Choose CertiPUR-US certified foams to avoid toxic chemicals

🔄 Bonus Tips for Upgrading Your Mattress Setup

• Add a Waterproof Mattress Protector: Protects your investment and helps with cleanup.

• Use a Ventilated Bunk Support Board: Foam mattresses on bunk platforms can trap moisture underneath. Use slats or a vented underlay.

• Consider a Mattress Topper First: Not ready to replace the whole thing? A 2” memory foam topper can make a big difference short-term.

• Allow for Expansion Time: RV mattresses often ship vacuum-sealed. Unbox them and let them expand for 24–48 hours before sleeping on them.
