Baby Doll Pretend Play Feeding Seat

It needs some DIY under the table where the two bars are at to make it sit level. Mine was from the Amazon Warehouse "Like New" and it was in the original packaging that was actually brand new looking, the item inside... not so much. I do not know if I got a damaged item in addition to a dirty item, or is this really how lopsided the item actually is? The photos show a chair that's level and this chair is really very much NOT level at all and will require some DIY to make it work. It's gross but I'll undo it all and wash it. I got it cheap enough that I'm just going to keep it, wash it, and if all else fails, I'll make a new seat to fit the metal frame. I will have to add a couple wooden blocks (or some other plan) under the desk because those metal bars underneath are oddly short on the up-angle and make the whole chair slant backwards with or without a doll in it. It doesn't matter if it's empty, if the doll is very lightweight stuffie, or if the doll is 3 pounds or so. I tested it with a 3 pound weighted doll, she's preemie size (wears some preemie brands of clothing pretty well), her hands just reach that strap that goes across to keep her from sliding out of the seat. It fits her nicely. Any doll much larger than that would look cramped I think (She is 17" or so in height, 3 pounds, preemie clothes fit her or are a little big, painted vinyl limbs/head with a cloth body, weighted with polyfil and glass pellets). Entire seat just leaned back and if I took my hand away it slowly began to slide just as it did when it was empty, or when it had a lightweight bear in it. Inside this "Like New" box, in addition to the odd stains that were on the bottom side/outer part of the whole thing, was a Peppa Pig tag from winter time. It's cute, might actually keep it lol, but definitely does not seem to be related to this item. I'd give it a higher rating if it actually didn't require me to DIY a way for it to sit level at the table/desk to keep it from sliding off onto the floor. Rating has nothing to do with Amazon warehouse/gross stains as that's not the doll chair maker's fault. Table and desk that I tested this on are both 5/8" thick. I have nothing else in the house to try it on that's a thicker table or desk unfortunately, so I don't know what sort of table this company tests on but it's apparently not this thin. I don't think I'd buy this brand again, unless it turns out this one's just defective with the arms under the desk then, yeah I would because I really like the flower one and I'd love if there was one that matched the blue series too but I didn't see a chair for that whole series. So I bought the cheapest one of them all I could find to give it a test and it's not gone well. Very disappointed. Unsure if other doll seats are the same with just different brand names on them or if they'll really be different.
