PERFECT GIFT: It’s a great little accessory for the favorite guinea pig cage in your life. The frame is made of wood and fixed with stainless steel screws. A “mat” or bed is made of a nice cotton fabric and a little stuffing Safe to chew: Pure untreated natural oak, a high quality wood used for furniture. Very strong and durable wooden bed frame. If there are pets or hamsters who like chew toys, they can be chewed safely and can last for more than a few months. Stable design: beautiful solid wood with cushion hammock , unlike a human hammock, it won’t knock your hamster to the ground if it bends the wrong way. It has a flat frame bottom and the frame prevents the fabric from spilling. Once assembled, it is both beautiful and stable EASY TO ASSEMBLE: The guinea pig hammock is pretty self explanatory. Easy installation without tools (installation instructions included). We recommend that you do not overtighten. This will make it easier to align the bolts where they need to go. When
