I wish I could find HEIMHOLZ last year when outdoor playgrounds were shut down and the only exercises left for my daughter were biking and walking in trails. Designed and handmade in Germany, HEIMHOLZ is combined with a frame with filings, a wooden slide and writing desk top. You can setup along with door frame or a stand alone by itself. It instantly becomes a climbing tree, a monkey bar and a slide, all in your house. With the additional of writing desk top, you can even work at on side while your kids play on the other side (only if you can enjoy this working-playing environment). The online store sells it in EU only for now. But you can find something similar from Etsy.
