- A TOP LAYER OF ORGANIC LATEX eliminates pressure points while facilitating air flow, providing EXCEPTIONAL COMFORT for all sleepers.
- A BASE LAYER OF POCKETED COILS provides the adaptive support and ergonomic alignment you need for a great night’s sleep, regardless of your age, size or sleep style, while reducing motion transfer between you and your sleep partner. And our construction uses NO FOAM encasement, providing exceptional airflow through the entire mattress to eliminate excess heat.
Buying Guide Highlights
- Don’t assume gel memory foam cools long-term; better materials include graphite, copper, latex, or micro-coils.
- Thickness impacts feel—thick toppers like Helix GlacioTex or ViscoSoft can shift firmness, so choose based on your desired feel.
- Try before committing—sleep trials (Saatva’s 180 nights, some offer 100+) help test cooling through real seasons.
- Watch for heat retention—memory foam without infusion may still trap heat despite cooling claims.
FAQs
Q: Does graphite or copper really cool the bed?
Yes—they help conduct heat away, especially when paired with breathable design or PCM layers.
Q: Is gel memory foam worth it?
Only for initial cool touch; it often loses effect quickly. Better to invest in graphite, copper, latex, or GlacioTex materials.
Q: Should I use a latex topper over memory foam?
Sometimes. A latex topper can improve airflow and support over dense foam setups.
Q: When is a topper a smart upgrade versus a new mattress?
If your mattress is still usable but overheats or lacks comfort, a topper can solve issues affordably—especially during sale periods.
