Our kids aren't falling out of bed anymore so we're selling our Safety First Bed Guard. Fully adjustable so it should fit most mattresses. The "jaws" that clamp on either side of the mattress open up to 11.5 inches so it can handle a mattress even a few inches thicker than that if you compress it a little. Easy to use and in good condition.
Feel free to call or email.
Thanks.
