What Matters Before You Choose a Corner Cut RV Mattress
Key buying criteria so you get the right fit the first time.
Measure your bunk
Corner cut sizes vary from 73 by 50 to 74 by 51. Measure the platform. Check dimensions.
Cut angle and side
The cut can be 21 or 22 inches and left or right. Measure the cut. Check the listing.
Thickness and clearance
Bunks often have limited headroom. Measure the gap. Beds in an RV sit under cabinets, slides and bunk frames, so even an inch of extra height can cause a rub or a blocked drawer. Compare the listed thickness with the gap you measured before ordering.
Foam type and feel
Memory foam contours, resilient foam bounces. Check the label. Dense memory foam sinks and holds heat while resilient foam springs back and sleeps cooler. Read the listing for foam type and density language before choosing a bunk mattress.
Washable cover option
Washable covers help with kids. Check the listing. Kids and pets make bunk covers dirty fast, and a zipper cover that goes in the washer saves replacing the whole mattress. Check the listing for a removable cover and its care instructions.
