We had a similar piece a while ago. The movers screwed the top to the bottom

There are also ways to attach it to the wall. Go to a hardware store and ask them what they have for that purpose. You are wise to ask.

I live in California and so many people attach heavy furniture to the walls so they are less likely to topple over in a quake. Even if there is no structural damage you can have unstable furniture fall over and cause damage.

Mine was done by a handyman type of person but If you are DIY, I am sure a good hardware store can advise you. I find that a good individual hardware store tends to have knowledgable help and i prefer it to the Big Box stires. I am lucky that there is a large well stocked one in my neighborhood. I realize these are a dying breed so i feel lucky that it still exists. 🤫

Just because someone wasn't injured by toppling furniture doesn't mean it doesn't pose a risk to children. When I was growing up there were no car seats - hell there weren't seat belts and as kids we used to stand up leaning on the front seat of the car. Cabinet doors didn't have childproof locks and sockets could theoretically electrocute a kid if they stuck something in there. Windows in high multiple level homes weren't required to have guards to prevent kids from falling out. Cribs had slats which could potentially strangle a kid and kids' sleep ware wasn't flame retardant. Paint had lead at one point as did actually paint on toys. My point is that the world has evolved to recognize certain things that are potentially dangerous and that relatively simple things could be done. Enough kids have fallen out of windows including Eric Clapton's son most famously do make this a fix that was implemented. In the same way enough furniture has topped over kids so that it is considered to be a potential hazard as I have seen warnings about it.

Furniture wall anchors or straps. My daughter pulled a top cabinet over and broke her leg when she was 4.

I grew up in a house full of "possible accidents" like this, never an issue. I helped my mother move our hutch back and forth from the kitchen and dining room as she rearranged the house to fit her newest idea. Each time we emptied it out, dusted, polished, etc. Having two pieces of manageable size was certainly easier than one tall unwieldy one. I also agree, we were taught to not climb on furniture, we climbed trees and fences outside. That being said, kids will be kids, they need to climb & stretch their imaginations. With so many more families living in urban areas and apartments maybe without immediate access to outdoor playgrounds, this is becoming more of an issue. My suggestion: A pair of straps of sorts screwed to the back of each piece straddling the joiint that can be unscrewed if/when you move.

My earlier reply seems not to have posted - here it is again:

This is potentially deadly. The two pieces should be attached to each other (I would suggest putting a sheet of plywood behind both, then screwing both halves to it) and then the whole thing should be attached to the wall with furniture straps due to the tipping risk.

I am glad other commenters survived dangerous situations. Those that didn’t, of course, aren’t here to comment. That might sound flip, but it isn’t - the concept of ”survivorship bias” makes people underestimate risks like these.

People dismiss the need for car seats, seatbelts, etc., but the truth is that a lot more people used to die or be maimed in accidents before we had these items.
