Expert review

The Sealy Sanctuary Oasis mattress combines pocket springs and foam in an effort to provide excellent, long-lasting support. We’ve found models from this brand to be a little hit and miss in the past, but this is one of the priciest we’ve tested, so it could be another hit. Read our Sealy mattress review for our expert verdict.
