QS 8.0 mattress

Looking to replace my 8.0 mattresses what size are they or what kind will fit and I still be able to close. Thanks

I have a 6.0 so the beds may differ; however, I am using a nice spring mattress off of a sofa sleeper and it works great!  You can get replacement sofa sleeper mattresses at many places.
