Size: Queen-60X80 IN
Easy install and excellent mattress support. Fits perfectly under a queen pillow-top mattress. Maintains the mattress completely quiet and prevents it from slipping. Extremely strong for being lightweight, keeping the mattress flat and firm without sinking. The installation is extremely easy: unpack and unfold, then place one section towards the headboard and the other towards the footboard.

Size: Queen-60X80 IN
I bought this bunkie board to add extra support to my queen mattress and it works exactly as described. It feels solid and supportive without adding much height to the bed. The material is sturdy, breathable, and completely silent with no creaking or shifting. I also like that it helps with airflow and doesn’t trap moisture. Setup was quick and easy. Overall, it’s a great, no-fuss solution if you need better mattress support.

Crazy easy to install, does not slide around. It is very strong. My bed had too big of spaces in between the slats and was causing back pain. This fixed it the first night.

These bunkie boards are heavy duty. They come set together inside these high quality fabric bags that just unfolds and lays flat. Perfect fit for twin size bed, no extra room left. Very hard, thick, and sturdy boards. Just lay onto bed and put mattress on top and ready for use.
