We don’t really have enough flat space for a full swing set structure in our backyard, but we are trying to think of another big-ish type of toy we could put in the backyard for our kids. They are 3.5 and almost 6 years old. I was thinking maybe a climbing dome? What do you have in your backyard that gets a lot of use, gives the kids something active to do get that sensory input, without giving you a heart attack that someone will break their neck?

I thought maybe something like these:
Kids Dome Climber Play Structures - Multiple Kids Jungle Gym Climbing Structure, Activity Center, Outdoor & Indoor Playground, Monkey Bars Climbing Tower - Age 3 - 10 Play Sets - 55 inches Mat https://www.amazon.com/dp/B07HGJBVW6/ref=cm_sw_r_cp_api_i_5A88Cb32BX6WX

Or this looks cool but too small for my kids:
