We got each of our kids the queen size of this mattress from Amazon for $249. Description: Mattress America Frost 13 Inch Hybrid Pocket Coil Pillow Top Mattress Gel Infused Memory Foam (Queen)
We find their mattresses comfy (and we have a new expensive mattress ourselves, lol). When one of the kids is sick or not feeling well, one of us parents either sleeps in their room with them or gets booted from our own bed. Honestly, it’s a really good mattress, and that’s before considering the price.
