I purchased this for my 6 yr old son's then-new low loft bed (also purchased on Wayfair). It is comfortable for him over a year later &, other than needing to let it air out a bit after the initial unwrapping, there have been no issues. I am actually purchasing this same product again for my 2nd child's new loft bed as well. The price is right, the mattress is a good fit for a bunk/low loft bed rail requirements, & is comfortable.
