A quality mattress topper can extend the life of a good mattress, fix a mattress that’s slightly too firm or soft, or add cooling properties to a warm sleeper. Here are the best toppers across every material and need.
Memory Foam Toppers: Best for Pressure Relief
Memory foam toppers add contouring softness to an innerspring or firm mattress. Best for side sleepers who need more shoulder/hip cushioning, or for those with a firm mattress that’s otherwise in good condition. Look for at least 3 inches of 4 lb/cu ft memory foam for meaningful pressure relief.
Top pick: Tempur-Pedic TEMPUR-Topper Supreme — the same TEMPUR material from their mattresses in topper form. Expensive but transformative for pressure relief.
Latex Toppers: Best for Cooling and Responsiveness
Latex toppers sleep significantly cooler than memory foam and have a responsive, bouncy feel. They’re the best option for hot sleepers who want added cushioning without increased heat. Natural latex toppers also carry some eco-friendly appeal.
Top pick: Saatva Zenhaven Talalay Latex Topper — premium natural Talalay latex that outperforms most competitors on cooling and durability.
Down and Down-Alternative Toppers: Best for Softness
Down toppers add a cloud-like softness layer. They don’t change support — just surface feel. Best for mattresses that are supportive but need a plush top surface. Not ideal for those who need actual structural pressure relief.
Wool Toppers: Best for Temperature Regulation
Wool naturally regulates temperature, wicking moisture away and helping maintain a neutral sleep temperature. Best for those who sleep hot in summer and cool in winter. Often used in organic/natural bedding setups alongside latex mattresses.
Cooling Gel Toppers: Best for Hot Sleepers
Gel-infused foam or copper-infused toppers actively pull heat away from the body. The Purple Mattress Harmony topper uses the same grid technology as the Purple mattresses for exceptional airflow.
How Thick Should a Mattress Topper Be?
2 inches: Minor comfort adjustment, light softening. Best for mattresses that are almost right but need a small tweak. 3 inches: Meaningful change in feel — significant pressure relief from a firm mattress. Most popular size. 4 inches: Major transformation — turns a firm mattress into something much softer. Can affect support if the underlying mattress is already worn.
What a Topper Cannot Fix
A mattress topper cannot fix a sagging mattress. Adding a topper on top of a mattress with a 1.5″ sag just creates a lumpy, sagging topper. If your mattress is sagging, you need a new mattress.
What to look for in a mattress topper
- A material that fits your goal: memory foam to soften, latex for responsive support
- 2–3 inches of thickness to meaningfully change the feel
- A firmness that corrects your current bed (softer or firmer)
- Cooling infusions if your current bed sleeps hot

Frequently asked questions
Can a topper fix a too-firm mattress? Yes — a 2–3 inch plush memory-foam or latex topper is the cheapest way to soften a bed that’s too hard.
Will a topper fix a sagging mattress? No — a topper masks minor wear but can’t repair a sagging support core. That needs a new mattress.
How thick should a topper be? Two inches for a subtle change, three or more for a big shift in firmness.
