Sit me up seat for 1 year old?

So when my daughter was born a year ago one of our gifts at our shower was a cute sit me up crab seat. She really only used it a handful of times and then my husband put it in the basement as it took up so much room and I completely forgot about it. I just came across it today and it does say the weight limit is 25lbs. My daughter is only 17lbs but she’s 14 months old and can sit totally fine. Would it be worth it to keep for her or would you say she’s too old for it? I feel bad since it was brand new and she literally used it maybe 7 times max.
