Frequently asked questions
What is the difference between Talalay and Dunlop latex toppers?
Talalay latex is whipped and baked, resulting in a softer, more uniform feel with better pressure relief. Dunlop latex is denser and firmer, often more durable and supportive. Both can be natural or blended.
How thick should a California king latex topper be?
For California king beds, standard thicknesses are 2, 3, or 4 inches. 2 inches is best for slight softness adjustment, 3 inches for significant change, and 4 inches for maximum plushness (may require deep-pocket sheets).
Are latex mattress toppers safe for people with allergies?
Natural latex is naturally resistant to dust mites and mold, making it a good choice for allergy sufferers. However, some people have latex allergies – look for GOLS-certified organic latex to minimize chemical exposure.
How long does a latex mattress topper last?
High-quality natural latex toppers can last 10-15 years or more, especially Dunlop latex. Lower-density or blended latex may wear out faster. Proper care, like using a waterproof protector, can extend lifespan.
Do I need deep-pocket sheets for a latex topper?
Yes, especially if the topper is 3 inches or thicker. Measure your mattress depth plus topper height and look for sheets with pockets that accommodate the total depth, typically 14-18 inches.

Overall, the Sleep On Latex Pure Green Natural Latex Topper is our top pick for its certified organic materials and reliable medium-firm support.
