Cut a new
Ikea mattress down to fit crosswise. Added
special underlayment to help airflow underneath the mattress. Added
incline wedges to offset the tilt of the van down toward the curb and to lift my head a bit to counter acid reflux while I sleep. I also reused two decorative bedrails Jeff made out of purpleheart wood, cutting them in half and making them retainers to keep the mattress in place.
