What to Look For

Focus on wool type and fill weight. Merino wool is finer and softer. Higher fill weight means more insulation. Check the cover material; cotton is breathable. Look for certifications like OEKO-TEX for safety.

Wool vs Down vs Synthetic

Wool naturally regulates temperature better than down or synthetics. It wicks moisture and resists odors. Down may be warmer but less breathable. Synthetics are cheaper but often trap heat. Wool is a balanced choice for year-round use.

Matching Your Sleep Style

Hot sleepers should choose a thinner topper with high breathability. Side sleepers need plushness for pressure relief. Back and stomach sleepers may prefer a firmer topper. Consider your mattress firmness as well.

Caring for a Wool Topper

Most wool toppers require spot cleaning or dry cleaning. Some have washable covers. Air them out regularly to maintain freshness. Avoid direct sunlight to prevent fading. Follow the manufacturer's instructions.
