Toddler bed mattress?

Jennie

My daughters crib and mattress were purchased for me. When she graduated to a toddler bed I just used the same mattress. I honestly never knew the crib/toddler mattresses could even cost $300. I think the one I have is on the cheap end and would like to buy my 2 year old a new one but every single mattress I’ve looked at has drastically good and bad reviews and I feel so overwhelmed. Help!
