Those who prefer a more neutral feel might find this mattress less appealing.

Material Preferences

  • Off-Gassing: A few users have mentioned an initial chemical-like smell, likely due to the fire retardant spray used on the mattress. This smell typically dissipates over time but can be bothersome initially.
