Yes, with one important limitation.
Electric heating pads and heated blankets can be used with Avocado mattresses at a low setting. Unlike polyurethane foam, organic latex does not retain heat, and because the latex layers sit beneath organic wool and ticking, there is no direct contact between the heating element and the latex itself.
Warranty notice: Extended or repeated use — including leaving a heating pad on all night — may cause discoloration of the exterior organic ticking over time. Discoloration from heat is not covered under the terms of our 25-year limited warranty. To protect your mattress, use a heating pad at a low setting for a limited time before sleep rather than running it throughout the night.
If your goal is to sleep warmer, an Avocado organic mattress topper adds a natural layer of insulation without risking heat buildup in the mattress underneath.
