Sealy Uniontown Plush Euro Mattress Set

Has anyone slept on one of these? Are they fairly soft for a side sleeper? I have an old Sears Sealy Emerald and am wondering if these are anything like they.

Does the king come with a split box spring? I see photos of a split but didn’t see any info? Thanks!

Vendor confirmed both the King and California King Sets come with a split boxspring.

What’s the difference between High Profile and Low Profile?

The box spring height.

High (9" Height)
Low (5" Height)
