Review on 🛁 madesmart Expandable Bath Shelf - White: Non-slip, Fits Most Tubs, BPA-Free by Neal Martin

I was worried it would be flimsy and difficult to adjust, but it slides very smoothly and the dark gray part stays on the bath tub well. We have a metal tub, but I think it would work well for a plastic tub as well. I love that it's plastic with holes so my little daughter can pour water into her cups without making a mess or I worry it will rust or mold like metal or bamboo. There are no sharp edges. The holes are small enough that my kids' fingers wouldn't go through them, but if they could, they'd be fine because even the plastic around them is smooth. He's calm too. I could borrow it from my kids for a book and a glass of wine.
