Meliusly Heavy Duty Bunkie Board King Size (76x80) - Non-Slip Breathable Bed Support Board for Slatted Bed Frame, Anti-Sag Under Bed Support, Noise Minimizing Moisture Resistant Bed Board

STOPS MATTRESS SAGGING BETWEEN SLATS — HEAVY DUTY DENSITY — Your mattress needs a flat, continuous surface to perform the way it was designed. When bed slats are spaced too far apart, the mattress sinks into the gaps — creating pressure points, uneven wear, and back discomfort. This Heavy Duty version features a higher-density 10mm twin-wall core for enhanced rigidity, bridging wider slat gaps with zero flex. Compatible with memory foam, latex, hybrid, and innerspring mattresses on platform beds, bunk beds, and any bed frame with slats or bars spaced up to 10 inches apart.
ULTRA-LOW 0.4” PROFILE — WON’T CHANGE YOUR BED HEIGHT — Traditional wooden bunkie boards add 1.5–3 inches of height and often show beneath the sheets. At just 0.4 inches thick, this board slides under your mattress and disappears. No visible edges, no height change, no refitting your sheets. The support your bed needs without changing anything about how it looks or feels.
NOISE-FREE, NON-SLIP DESIGN — STAYS PUT WHILE YOU SLEEP — Oxford fabric covering eliminates wood-on-metal creaking. Silicone grip on the bottom locks the board to your slats — no shifting, no sliding, no readjusting. Place it once and forget it.
PROTECTS YOUR MATTRESS & EXTENDS ITS LIFE — Many warranties require slat spacing under 3 inches. This board creates the continuous surface manufacturers recommend. Breathable, moisture-resistant construction prevents the hygiene issues sealed wooden boards can cause.
60-SECOND SETUP — NO TOOLS NEEDED — Unfolds flat and installs in under a minute. King, Queen, Full, and Cal King come in two sections placed side by side; Twin and Twin XL are single pieces. Sized to match standard mattress dimensions exactly. Questions? We’re a small family business that reads and responds to every single message.
