Is it damaging to compress the sides of a memory foam mattress?

We are driving from Jersey to Chicago for a funeral, so plans have been made hastily. The idea is to take my queen size memory foam mattress (~57” wide) and squeeze it into the back of my minivan (~50” wide). The minivan has a metal loop sticking out of each side where the rear seat clips on when it is folded into place. It is impossible to fold these loops down or to remove them temporarily. The loops, in the place where they stick out, recude that 50” to 44”.

Would the mattress be damaged by 1) the side compression in general, or 2) by the extra-severe compression with the small surface area of the metal loops?

I know that memory foam gets shipped compressed, but I assume that that compression is more or less even across the entire mattress. I can’t seem to google up any info about compressing it unevenly. Any thoughts or experience in this, guys?
