Memory foam has a reputation for swallowing you, and this mattress does not. The Chime 12 Inch lands on the firm side of its medium firm label, with a tight top and a support base that keeps you up on the surface rather than down in it. Back and stomach sleepers tend to take to that immediately; if you want to sink into a cloud, plan on a topper.
That firmness isn't why it's our top pick, though it doesn't hurt. It's the top pick because almost nothing about owning it is a gamble. The foam is CertiPUR-US certified, the warranty runs ten years and is not prorated rather than limited, and the support base is substantial enough that the mattress holds its shape when you sit up to read. We gave it the full 48 hours to expand before judging it, and what we got was a bed that stays put: no roll-together in the middle and no hollow where the heavier sleeper lies.
Two practical notes before you order. It's a full at 74 by 52 inches, so it suits a small room or a guest space rather than a couple's master, and it's rated for an adjustable base, which not every foam bed at this level is. The cover is a tight-top polyester with spot-clean care, so buy a protector the same week — it's the single thing that decides whether a foam mattress still looks new in three years.
Bottom line: We recommend it as the default mattress here: firm, supportive, certified foam and a non-prorated ten-year warranty, with the deepest track record of anything in this guide.
