When you're choosing a mattress topper for someone who spends a lot of time in bed, comfort is only part of the decision. Temperature, pressure relief, hygiene, and how the materials are made all matter too. Here's a clear, practical comparison of sheepskin and memory foam so you can make the right call, whether you're choosing for yourself or someone you care for.

Quick Answer
Sheepskin is the better choice for anyone who sleeps hot, prefers natural materials, or needs gentle pressure distribution for skin and joint comfort. Memory foam suits a tighter budget, someone who needs firm, deep contouring support, or a household where easy cleaning is a priority.
Both materials relieve pressure. The right one depends on the specific needs of the person sleeping on it.
How They Work
How sheepskin works
Sheepskin is made from the full fleece of a sheep, with the wool fibres intact and attached to the hide. The individual fibres are hollow and crimped, which creates millions of tiny air pockets. Those air pockets do two things: they cushion the body by spreading weight across a larger surface area, and they let moisture and heat move away from the skin rather than building up.
Medical-grade sheepskin is denser and firmer than decorative sheepskin. It's made for prolonged contact with skin, including in pressure care settings. To learn more about what sets medical-grade apart, see our guide on Medical Grade Sheepskin Explained.
How memory foam works
Memory foam is a synthetic material that softens in response to body heat and weight, moulding closely around the person lying on it. This creates a cradling effect that takes pressure off areas like hips, shoulders, and heels.
The trade-off is that the same density that makes it supportive also traps heat. Memory foam doesn't allow much airflow, so heat and moisture build up between the sleeper and the surface. For someone who already sleeps warm or gets night sweats, that can become a real problem.
Side-by-Side Comparison
| Factor | Sheepskin | Memory foam |
|---|---|---|
| Temperature | Regulates naturally; stays cool in summer, warm in winter | Retains heat; can feel uncomfortably warm overnight |
| Pressure relief | Distributes weight across fibres; gentle and consistent | Deep contouring; high relief at specific pressure points |
| Moisture wicking | Excellent; fibres draw moisture away from the skin | Poor; moisture stays trapped against the surface |
| Hygiene and care | Wool resists bacteria and mould naturally; hand or gentle machine wash; needs more care | Spot clean only for most foam products; easier to maintain day to day |
| Natural vs synthetic | Natural; no synthetic chemicals needed for fire resistance or structure | Petroleum-based; can off-gas VOCs; requires chemical flame retardants |
| Durability | Maintains loft for years with proper care; shaking restores shape | Compresses over time; may need replacing sooner |
| Cost | Higher upfront cost | Lower upfront cost; more frequent replacement |
Who Should Choose Which
Sheepskin is a better fit if
- You sleep hot or wake with night sweats
- There are concerns about skin breakdown, redness, or early pressure injuries
- Chemical sensitivity or a preference for natural, chemical-free materials matters
- You or someone you care for spends extended time in bed and needs gentle, breathable support
The Sheepskin Bed Topper Overlay is a solid place to start. It uses medical-grade sheepskin designed for comfort and skin protection, and it sits securely over the mattress to stay in place through the night.
If you're not sure which sheepskin topper suits the bed and the situation, our guide on How to Choose a Sheepskin Mattress Topper in Australia walks through sizing, density, and what to look for.
Memory foam is a better fit if
- Budget is the main consideration and you sleep cool
- You need firm, deep contouring support and sleep on the heavier side
- Easy cleaning and low-maintenance bedding is a priority
- Temperature regulation isn't a concern
