I bought a couple of Sinnerlig table lamps from IKEA last year.

I bumped the glass cover on one with something (I think when putting my phone down, it was barely a tap) and it cracked a bit...a bit too readily tbh.
Then the other day I bumped the cover off it and it fell about half a metre onto a thick bedroom carpet and shattered into shards.
I was going to contact IKEA about it maybe unsuitable for places like kids bedrooms, but you can't do that without the receipt and a pile of other not readily available details.
I hate that.
