When bed slats are spaced too far apart, the mattress sinks into the gaps creating pressure points, uneven wear, and back discomfort. This 10mm twin-wall support board bridges those gaps, giving your mattress the foundation it needs. Our bunkie board requires a structure underneath, such as a metal frame or bed slats. Its capacity depends on the support structure. 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 This board creates the continuous surface manufacturers recommend, compatible with memory foam, latex, hybrid, and innerspring mattresses on any bed frame with slats or bars spaced up to 8 inches apart. Many warranties require slat spacing under 3 inches this closes that gap and protects yours. Breathable, moisture-resistant construction also 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.
