Best Mattresses for Tall People
Sleepers 6'2" and taller need an 84-inch California King, a deeper foot-end support zone, and edges that hold up when an arm or leg hangs off. These 8 picks passed all three tests in our Encinitas lab.

California King vs. Standard King for Tall Sleepers
A standard King is 76″ wide × 80″ long. A California King is 72″ wide × 84″ long — it trades 4 inches of width for 4 inches of length. For sleepers 6'2″ and taller, that extra foot-room is non-negotiable: hanging feet over the edge crushes the foot-end foam encasement within 6–12 months and tilts the heels below the heart, which interferes with venous return.
- Choose Cal King if either partner is 6'2″+ and you sleep mostly back or side.
- Choose Split King (two Twin XL halves at 76″ × 80″) if one partner needs a different firmness or an adjustable base.
- Confirm the brand publishes a true 84″ length — a handful of boxed brands quietly cap at 82″.
- Pair with a bed frame rated for 84″ — standard King frames will not fit a Cal King mattress.
