Dwarf Rabbits & Rabbit Proofing Question

We have two Netherland Dwarf sweeties. They are playful and fun but we find that every time we let them out of the pens, they play a bit and then disappear under the reclining sofa, sectional, or other pieces of furniture and we spend forever trying to get them out.

I'm at a loss for how to prevent them from going under the furniture and am hoping that someone else with smaller breeds has overcome this challenge without having to use every blanket in the house and then monitoring every section to make sure they don't dig it out of the way when you turn your head.

If not for the fact that the furniture reclines, it would all sit lower to the ground. But... it is what it is. And little bunnies, well, they fit EVERYWHERE! lol

Tunnels and cardboard boxes along the edges. However that only works so well if your Nethies are anything like mine who went where he wanted even if blocked off he found a way!

Many people use carboard, pens, NIC panels etc. to block off areas for bunny proofing. It's always a good idea to watch the buns too, to make sure they don't find a way past all your hard work. Nethies are too smart for their own good, if you ask me.

it may not be an attractive fix but you could put pieces of 2 X 4's around the edges of the furniture
