NM 6" Firm Tight Top Foam Mattress - Double/Full

Q: What are the exact dimensions of this 6 inch mattress?

This mattress is approximately 6 inches high and is available in standard width and length sizes such as Twin, Twin XL, Full, Queen, or RV specific dimensions. Check the size chart on the product page for exact width, length, and height measurements.

Q: Do I need a mattress protector for a full size mattress?

A mattress protector is highly recommended. It helps keep the full size mattress clean by guarding against spills, sweat, dust, and allergens, and it can significantly extend the life of the mattress in kids' rooms, guest rooms, or primary bedrooms.

Meet NM® HD+™ Core—mattresses built around high‑density foam for durable support, low motion transfer for quieter nights, zoned lumbar for alignment, and reinforced edges for full‑width comfort. Available in firm, medium, and plush feels across Twin, Twin XL, Full/Double, Queen, and King.
