Buying advice: mattress toppers
- 1Memory foam suits pressure relief — latex suits a responsive feel and durability, fiberfill suits a soft, pillowy top layer.
- 22 inches changes the feel noticeably. 3 to 4 inches gives more pressure relief for side sleepers.
- 3Side sleepers usually prefer softer toppers for shoulders and hips. Back and stomach sleepers need firmer support to avoid sinking.
- 4Traditional memory foam traps heat. Gel infusions, open-cell foam and latex help hot sleepers.
- 5Toppers with straps or a fitted cover are less likely to slide. Foam toppers often off-gas a smell for a few days after unboxing.
