So I've had this problem due to my doll's weight. She's roughly 130lbs and 168cm. So storing her has been a issue. I was using her box for the longest time but getting her in and out from the floor has been absolutely torture on my back due to her weight. So I decided to find a way to hang her in a spare bedroom closet. I found a iron clothes hanging rack that can easily support her weight. Her height was a issue so I put 2 cinder blocks underneath so her feet would clear thexdoll supply website that had basically the same stuff for a far greater price (around $400). I found this rack on Amazon for about $80. The 72" wedding dress/linen bag to keep her clean and the dust off her for $12, a 1 foot chain and shackle and cinder blocks from Home Depot for about $12. And the stainless doll hook set on Amazon for $15. This saved me a ton of money rather than ordering from a doll supplier. The bag will truly help keep her clean and free of pet hair and dust. I forgot about hanging her head also, so I will by another hook set so I can keep her head with her. This has truly been a game changer for me! Hope this helps with anyone else struggling with this issue.
I have similar issues with the weight of my girl "Bambi" She spends her time strapped down to a 2 wheel hand truck aka furniture dolly, or more precise I could call it a "dolly dolly" with a couple of bungie cords she just stands there watching me and waiting for her next adventure. I have her wearing a wrap around swim suit cover up. I use this because it doesn't require me to slip it over head and pull it over her. You just slide it over 1 arm wrap it around then slip over the other arm, then with a tie added around the waist to keep it in place. It cost less than $10 too.
