Mytee Products Foam Mattress - 33" Wide x 84" Long Replacement Truck Sleeper, Double-Sided Comfort, Quilted Bed Mattress, 5" Thick, Replaces MR3384

Product Overview

This mattress measures 33 inches wide by 84 inches long with a 5-inch thickness, designed specifically to replace OEM part MR3384 in truck sleeper compartments. The construction uses a single-layer foam core described as comfort foam, covered with non-woven fabric that creates a simple, durable surface. The double-sided design allows users to flip the mattress periodically to distribute wear evenly across both surfaces. The medium firmness provides balanced support suitable for various sleep positions without excessive softness that might compromise durability. Weighing 15.2 pounds, the mattress remains manageable for installation and removal during maintenance. The non-woven fabric cover resists basic wear but lacks advanced features like waterproofing or quilted padding. This mattress ships as a single unit in packaging measuring 18 inches in all dimensions. It targets adult users in commercial driving environments where reliability and straightforward replacement take priority over premium comfort features. The warranty covers 18 months from purchase or 100,000 miles of vehicle use, whichever comes first, reflecting its intended heavy-duty application.

Design & Build

The mattress employs a straightforward single-layer construction with comfort foam as the core material. This foam provides the medium firmness noted in specifications, creating a supportive yet not overly rigid sleeping surface. The non-woven fabric cover wraps the foam completely, offering basic protection against dirt and moisture while maintaining breathability. The double-sided design means both surfaces feature identical cover material and foam density, allowing users to flip the mattress when one side shows wear. This practical approach extends usable life in high-frequency environments like truck sleeping compartments where mattresses experience regular use. The edges are squared rather than contoured, maximizing the usable sleeping area within the 33×84-inch footprint. The 5-inch thickness represents a standard profile for replacement truck mattresses, providing adequate cushioning without excessive bulk that might interfere with sleeper compartment closures or storage.

Maintenance remains simple due to the basic materials. The non-woven cover can be spot-cleaned with mild detergents, though it lacks waterproof or stain-resistant treatments. The foam core should be kept dry to prevent mold or deterioration. The mattress ships compressed in packaging measuring 18 inches in all dimensions, requiring unboxing and full expansion before use. The 15.2-pound weight makes it manageable for one person to position within a truck sleeper. No handles or carrying aids are integrated, reflecting its stationary installation purpose. The design prioritizes functional durability over aesthetic details, with no quilting, padding layers, or decorative elements. This approach keeps costs reasonable while delivering reliable performance for replacement scenarios where the original mattress has worn out.

Performance

The medium-firm foam provides consistent support across the sleeping surface, maintaining its shape under regular use. The single-layer construction avoids the potential for layer separation or uneven wear that can occur in multi-layer mattresses. The foam density balances comfort with durability, offering adequate pressure relief for most sleepers without developing permanent body impressions quickly. The non-woven cover breathes reasonably well, reducing heat retention compared to vinyl or plastic covers, though it lacks advanced cooling technologies. In truck sleeper environments where temperature fluctuations occur, the simple materials help maintain a stable sleeping surface. The double-sided design effectively doubles the usable lifespan by allowing periodic flipping when one surface shows compression or wear patterns. This performance characteristic proves valuable in commercial settings where mattresses receive nightly use.

Durability aligns with the warranty period of 18 months or 100,000 miles, suggesting the mattress withstands regular use within that timeframe. The foam resists sagging and maintains its supportive properties through typical truck vibration and movement. The cover material holds up to basic abrasion from sheets and bedding, though it may show wear faster than heavier-duty fabrics. Condensation or moisture resistance depends entirely on keeping the mattress dry, as the materials lack inherent waterproofing. The squared edges maximize the usable sleeping area, providing full support to the mattress perimeter. Weight distribution remains even across the surface, preventing roll-off or edge collapse during sleep. The performance profile suits replacement purposes where reliability and straightforward functionality matter more than luxury features or advanced comfort technologies.
