My daughter loves this bed! We got an 8 thick memory foam mattress for the top and a 7 think memory foam mattress for the trundle and they are both perfect for a kid or an adult. There is a lot of space on the sides but we just use the decorative pillows and skipped buying a bumper since she is 4 years old and that works fine. Directions were great, arrived in good condition, I highly recommend this bed!
