Quick Answer: The best blanket material depends on whether you sleep hot or cold. Cotton and linen are best for hot sleepers (breathable, moisture-wicking). Wool and fleece are best for cold sleepers (insulating, warm). Weighted blankets use glass beads in cotton shells for anxiety relief. For year-round versatility, a medium-weight cotton blanket paired with a duvet you can add or remove works best.

Cotton Blankets
Cotton is the most versatile blanket material and the safest choice if you are not sure what you need. It breathes well, wicks moisture, gets softer with washing, and works in all seasons. There is a reason hospitals and hotels default to cotton.
Cotton Weave Types
Cotton Blanket Varieties
- Thermal weave (waffle): Open, breathable weave with a textured grid pattern. Traps air in the pockets for warmth while allowing airflow. Ideal for spring and fall
- Herringbone: Tight diagonal weave that is slightly heavier than thermal. More structure and drape. Good all-season weight
- Matelasse: Quilted or textured cotton with a raised pattern. Decorative and functional. Medium warmth, good for layering
- Muslin: Lightweight, loosely woven cotton. Very breathable. Best for summer or as a light layering piece
Dorothy, our sleep specialist, often recommends cotton for customers transitioning between seasons: "A cotton thermal blanket is the one blanket that works from May through October in Brantford. You can use it alone on warm nights or layer it under a duvet when it gets cool."
Cotton and Temperature Regulation
Research by Shin et al. (2016) published in Nature and Science of Sleep found that cotton bedding produced lower skin temperatures and humidity at the skin-fabric interface compared to synthetic alternatives. Participants sleeping with cotton bedding at 22 degrees Celsius reported significantly fewer awakenings and better subjective sleep quality. Cotton's natural ability to absorb moisture (up to 25% of its weight) and release it through evaporation helps maintain the skin microclimate in the optimal range for sleep.
Fleece and Microfibre Blankets
Fleece blankets are made from polyester and are the go-to for warmth at a low price. They are lightweight, machine washable, and available in every colour and pattern imaginable. The downsides are heat retention and static buildup.
Fleece vs Microfibre Plush
Standard fleece has a smooth, slightly fuzzy surface. Microfibre plush (sometimes called velvet plush or sherpa) has a denser, softer pile. Both are polyester, but the fibre structure differs. Microfibre plush feels more luxurious but is more delicate. It pills and mats faster than standard fleece if washed incorrectly.

When Fleece Works Best
Fleece blankets are excellent for the couch, guest bedrooms, camping, and car travel. They are warm, lightweight, and inexpensive enough that you do not worry about wear. For primary bedding, however, hot sleepers should avoid fleece as their main blanket because it traps body heat against the skin. Pair fleece with a well-ventilated room (below 19 degrees Celsius) if using it as your sleeping blanket.
Wool Blankets
Wool is the original performance fabric. It regulates temperature in both directions: warm in cold conditions and cool in warm conditions. Wool fibres are naturally hollow, creating insulating air pockets, and the lanolin content gives wool natural moisture resistance and antimicrobial properties.
Types of Wool for Blankets
Wool Varieties Compared
- Merino wool: The softest wool type. Fine fibres (under 24 microns) feel smooth against skin. Excellent temperature regulation. More expensive ($150-400 for a queen blanket)
- Lambswool: First shearing from young sheep. Soft and resilient but slightly less fine than merino. Mid-range pricing
- Standard wool (Cheviot, Romney): Coarser fibres. Very durable and warm but can feel scratchy against bare skin. Best used inside a duvet cover
- Cashmere: Ultra-fine goat hair. Exceptionally soft and lightweight. Very expensive ($300-800+). Requires gentle care
- Alpaca: Softer than sheep's wool, hypoallergenic, and warmer per ounce. Good for people who find sheep's wool itchy
Our Restonic Luxury Silk and Wool mattress at $1,395 for a queen uses natural wool and silk fibres in the comfort layer for the same temperature-regulation benefits, built right into the sleeping surface.
Wool Care
Most wool blankets should be dry cleaned or hand washed in cold water with a wool-specific detergent. Machine washing on a wool cycle works for some types but check the care label. Never wring wool. Roll it in a towel to extract moisture and lay flat to dry. Heat and agitation cause felting (irreversible shrinkage).
Weighted Blankets
Weighted blankets use glass microbeads or plastic pellets sewn into small pocketed compartments to distribute 5-30 pounds of weight evenly across the body. The deep pressure stimulation mimics a firm hug, reducing nervous system arousal and promoting relaxation.
The Science Behind Weighted Blankets
A randomized controlled trial published in the Journal of Clinical Sleep Medicine by Ekholm et al. (2020) found that participants using weighted blankets experienced a 67% reduction in insomnia severity. A subsequent study by Meth et al. (2023) in the Journal of Sleep Research found that weighted blankets increased melatonin production by 32% compared to light blankets. The mechanism is deep pressure stimulation, which activates the parasympathetic nervous system and promotes the transition from sympathetic (alert) to parasympathetic (rest) dominance.
Choosing the Right Weight
The standard recommendation is 10% of your body weight, plus or minus a pound. A 150-pound person would start with a 15-pound blanket. Going too heavy can feel restrictive rather than comforting, especially for side sleepers who need to turn freely.
Brad notes a common mistake: "People buy a 25-pound weighted blanket because they think heavier is better. Then they cannot turn over at night, and their shoulders ache in the morning. Start lighter. You can always go heavier."
Linen, Bamboo, Silk, and Down
Linen
Linen is made from flax fibres and is even more breathable than cotton. It has a slightly rough texture when new that softens dramatically with washing. Linen regulates temperature exceptionally well and absorbs moisture up to 20% of its weight without feeling damp. The downside is cost ($100-300 for a queen blanket) and wrinkle tendency.
Bamboo Viscose
Bamboo blankets are made from bamboo pulp processed into viscose or rayon fibres. They are silky smooth, naturally hypoallergenic, and breathe well. However, the manufacturing process is chemical-intensive, so the "eco-friendly" marketing around bamboo textiles can be misleading. Check for OEKO-TEX certification to ensure the finished product meets safety standards.
Silk
Silk blankets are lightweight, temperature-regulating, and feel luxurious. They are also expensive, delicate, and require dry cleaning. Silk works best as a thin layer under a duvet rather than as a standalone blanket. The natural protein structure of silk is hypoallergenic and resistant to dust mites.
Down and Down Alternative
Down is not a blanket material per se, but a filling used in duvets and comforters. Goose down provides the highest warmth-to-weight ratio of any insulation material. Down alternative (polyester fill) mimics the loft at a lower price point and is hypoallergenic. For care guidance, see our duvet drying guide.
How to Choose the Right Material
Blanket Material by Sleeper Type
- Hot sleepers: Cotton (thermal weave or muslin), linen, or bamboo viscose. Avoid fleece and heavy wool
- Cold sleepers: Wool (merino or standard), fleece, or a down duvet. Layer a cotton blanket underneath for moisture management
- Allergy sufferers: Bamboo viscose, silk, or synthetic down alternative. Avoid wool unless you have confirmed you are not sensitive to lanolin
- Anxiety or insomnia: Weighted blanket (cotton shell with glass beads) at 10% of body weight
- Budget-conscious: Cotton thermal blankets ($25-60) or fleece ($15-40) offer the best value for the price
- Year-round versatility: Cotton thermal blanket as a base layer, add or remove a duvet seasonally
Seasonal Blanket Strategy for Ontario
Brantford's climate runs from humid summers (25-35 degrees) to cold winters (down to minus 20). A practical approach is three layers: cotton thermal blanket year-round, plus a lightweight duvet for spring and fall, plus a heavy duvet or wool blanket for winter. This layering system lets you adjust nightly without buying different blankets for each season. Many of our customers in the Grand River Valley use this exact setup with great results.

Frequently Asked Questions
What is the warmest blanket material?
Wool provides the best warmth-to-weight ratio among blanket materials. A merino wool blanket weighing 2 pounds can provide the same warmth as a 4-pound fleece blanket. For maximum warmth with minimal weight, a goose down duvet is the warmest option, though it is a comforter fill rather than a blanket material.
What blanket material is best for summer?
Cotton muslin or a lightweight cotton thermal weave blanket. Both allow airflow while providing just enough coverage for comfort. Linen is also excellent for summer but costs more. Avoid polyester fleece and heavy wool in warm months.
Are bamboo blankets better than cotton?
Bamboo viscose is smoother and slightly more moisture-wicking than cotton, but cotton is more durable, more affordable, and easier to care for. Bamboo blankets pill more easily and the manufacturing process is chemical-intensive. For most people, cotton offers better overall value.
How heavy should a weighted blanket be?
Start with 10% of your body weight. A 150-pound person should try a 15-pound blanket. If you share a bed, each person should have their own weighted blanket sized to their body weight. Weighted blankets should not be used for children under 3 or anyone who cannot independently remove the blanket.
