A memory foam topper is the most popular way to soften an existing mattress -- and at $80-$250, it's dramatically cheaper than a new mattress. Here's what actually differentiates quality memory foam toppers from cheap ones.
What to Look For in a Memory Foam Topper
- Density: 3-5 lb/ft3 is ideal. Below 3 lb/ft3 wears out quickly (2 years or less); above 5 lb/ft3 is too firm and slow to respond
- Thickness: 2-3 inches for meaningful feel change; 1 inch for very minor softening only
- Certifications: CertiPUR-US certified means no harmful VOCs, formaldehyde, or heavy metals
- Cooling features: Gel-infused, open-cell, or copper-infused foam for temperature regulation

Frequently asked questions
Our top pick at this material
Saatva Contour5
Gel-infused all-foam with lumbar alignment zone. Queen $2,599 with current $400 off.
All-foam mattress pros and cons?
Pros: best motion isolation, contoured pressure relief, quiet, usually lightest option. Cons: heat retention (solved by gel or graphite infusion), slower response (classic memory foam "stuck" feel), shorter lifespan than hybrid or latex. The Saatva Contour5 is a gel-infused all-foam that sidesteps the heat problem.
How long does memory foam last?
6–10 years. High-density memory foam (4+ lbs/cu ft) lasts longer than low-density (2–3 lbs). Cheap memory foam develops permanent body impressions within 2–3 years.
Is memory foam hot?
Yes — base memory foam retains body heat. Modern gel-infused, graphite-infused, and open-cell memory foams reduce but don't eliminate the issue. Hot sleepers should pick hybrid or latex, not all-foam.
Our top topper pick
Saatva Graphite Memory Foam Topper — from $225
Graphite-infused cooling, available in 1.5", 2", and 3" thicknesses. 180-night trial, free white-glove delivery. The default pick whether you need pressure relief, cooling, or a stopgap for a too-firm mattress.
Will a mattress topper save a mattress that's too firm?
Yes — a 3" topper (memory foam or latex) meaningfully softens a mattress that's 1–2 firmness levels too firm. Works especially well on hotel-style mattresses that prioritize durability over comfort. Our default: Saatva Graphite Memory Foam Topper.
How much does a good topper cost?
$150–400 for 3" cooling memory foam or Talalay latex. Below $100 = thin, quick to flatten. Above $400 = diminishing returns unless you're buying natural certified organic latex.
Do mattress toppers void the mattress warranty?
Usually no — but a topper that traps heat and causes foam degradation can void the warranty. Use a breathable topper (avoid vinyl-backed) and you're fine.
| Feature | Memory Foam Topper | Latex Topper |
|---|---|---|
| Feel | Slow-responding, conforming | Bouncy, responsive |
| Cooling | Moderate | Better |
| Durability | 2-4 years | 4-8 years |
| Price | $80-$250 | $200-$500 |
| Motion isolation | Excellent | Good |
For the best durability and cooling, the PlushBeds Natural Latex Topper ($299 queen) outlasts any memory foam topper by 2-3x and sleeps significantly cooler.
Frequently Asked Questions
Does a memory foam topper make a mattress hotter?
Traditional petroleum-based memory foam does trap heat. Gel-infused, open-cell, or plant-based memory foam toppers sleep noticeably cooler. If heat retention is a concern, consider a latex topper or a gel/plant-based foam topper instead of standard memory foam.
How thick should a memory foam topper be?
2 inches for moderate softening and feel change. 3 inches for significant softening -- can make a firm mattress feel medium. 4 inches is the maximum practical thickness; anything thicker can affect mattress support and stability.
Mattress topper buying guide
A quality mattress topper extends the life of your existing mattress by 2-3 years and can adjust firmness by 1-2 levels on a 10-point scale. Here is what to look for.
Topper material options
- Memory foam — maximum contour and pressure relief. Best for side sleepers with hip or shoulder pain. 2-4 inch thickness is standard.
- Latex — responsive, cooling, durable. Best for sleepers who want support without the sinking feeling.
- Wool — temperature-regulating, natural. Thin toppers (1 inch) for temperature control; not for firmness change.
- Down / feather — plush, cloud-like. Adds softness but not support; pairs well with firm mattresses.
- Gel-infused foam — contour with better heat dissipation than traditional memory foam.
Topper thickness guide
- 2 inches — subtle comfort upgrade, minimal firmness change.
- 3 inches — most popular thickness, noticeable feel change.
- 4 inches — significant firmness adjustment, best for converting a too-firm mattress to medium.
How long toppers last
Memory foam and latex toppers last 3-5 years. Down toppers last 2-3 years. Polyester toppers flatten within 12 months.
