If you want to drive yourself nuts, go shopping for a new mattress. You’ll hear dozens of theories on coils, fabrics, stuffing, foam density and warranties.
What I know about buying a mattress I’ve learned from the best: Insiders now retired from the sleep product industry.
All of the major brands—Simmons, Serta, Sealy, etc., make decent mattresses but if you’re planning to go from one chain store to the next comparing prices, forget it. The major brands change the names of the same mattress for each of the stores so it is impossible to compare by make and model.
SHOP BY LEVEL
Each company makes “levels” of mattresses: Very cheap, decently cheap, good and best. That’s not what they call them, but you can tell by the pricing within each manufacturer’s line of products. Expect several models in each price level.
