Mattress Buying Guide: Types, Firmness & What to Compare

A mattress is the biggest purchase in your bedroom, and online brands make it easy to get overwhelmed by “best ever” claims. The good news: a few factors — mattress type, firmness for your body and sleep position, and the trial and warranty terms — narrow the field quickly. Here’s how to think about each.

The four main mattress types

TypeFeelStrengthsTrade-offs
All-foam (memory foam)Contouring, “hug”Pressure relief, motion isolation, usually lower priceCan sleep warm; weaker edges; slower to change positions
HybridBalanced, a bit of bounceCoils add airflow, edge support, and responsivenessHeavier and usually pricier than all-foam
LatexBuoyant, springyDurable, responsive, sleeps cooler than most foamsHeavy; natural latex is expensive
InnerspringBouncy, firm surfaceBreathable, familiar feel, budget-friendlyLess pressure relief; can transfer motion

Firmness: match it to how you sleep

  • Side sleepers usually need a softer-to-medium surface so shoulders and hips can sink in.
  • Back sleepers tend to do best on medium to medium-firm, which supports the lower back.
  • Stomach sleepers generally need firmer support to keep the hips from sagging.
  • Body weight matters too: heavier sleepers often find a mattress feels softer than its label, while lighter sleepers find it firmer.

Other things worth comparing

  • Temperature: coils, latex, and open-cell or plant-based foams usually sleep cooler than dense traditional memory foam.
  • Edge support: important if you sit on the edge of the bed or share a smaller mattress.
  • Motion isolation: all-foam beds are typically best if a partner’s movement wakes you.
  • Certifications: look for CertiPUR-US for foams, and GOLS or GOTS if you want certified organic latex or cotton.

Read the trial and warranty fine print

Most online brands offer an in-home sleep trial — often 100 nights or more — but the details vary. Check whether returns are free, whether there’s a minimum break-in period before you can return, and whether pickup or restocking fees apply. For warranties, look at the sag depth that counts as a defect and whether coverage is full replacement or prorated in later years.

Typical price ranges (queen)

As a rough guide: under about $1,000 for budget all-foam beds, roughly $1,000–$2,000 for most mid-range foam and hybrid models, and $2,000 and up for premium hybrids and natural latex. Frequent sales mean list price is rarely what you’ll actually pay.
