Buying Guide

Measure your sleeper cab

Measure length, width and any cutouts in your truck sleeper cab before buying to ensure mattress dimensions (e.g., 30x72 or 32x75) will fit without modification

Match thickness to space and support

Select a thickness that fits your headroom and support needs—options here range from 4 to 7 inches, with thicker models generally providing more pressure relief

Choose foam type for comfort and temperature

Memory foam delivers contouring support, while gel-infused memory foam offers added cooling—use gel options if you sleep warm or spend long periods in the cab

Prioritize compact, bunk-friendly designs

Look for mattresses labeled for RV, bunk, or camping use since they’re built to fit narrow, shorter, or oddly shaped truck sleeper berths

Balance rating and price

Consider customer ratings (products listed range around 4.4–4.6 stars) alongside price points ($139.97–$189.97) to find the for your sleeper cab
