We bought a used RV, needed to replace an odd size mattress.  This mattress had the best ratings & looked like we could cut it to fit, if needed, without spending a lot more money for a mattress that was not going to fit our needs.
The mattress fluffed up quickly after being released from the packaging, & we do not have to trim the edge for it to fit the odd size frame.  
It is a little plush for me, but my husband likes it.
