Feather or down toppers are a good choice if you are looking for softness. The feather and down material snuggles your body and makes for a cozy night's rest. Tossing and turning while sleeping is lessened because of the cradling effect of the down or feathers. However, if you are looking for support or do not already possess a firm or medium-firm mattress, the feather or down mattress topper might not be the best choice, especially if you suffer from back or posture problems.
For those who suffer from allergies, many brands of feather or down toppers offer non-allergenic covers or solutions. There are also down alternative pillow toppers for those allergic to feather or down.
Because these toppers are made with natural materials, they breathe easier, and are as usable in the summer as they are in the winter.
Wool is actually one of the best options for those looking for softness and a sense of coziness. It is naturally hypo-allergenic and resistant to dust mites. Wool or a wool blend also regulates body temperature, so may even be a good choice for hot summer months.
There are many options for wool types (from alpaca to lambswool) and wool blends (such as cotton-wool blends) that allow for a variety of softness and warmth.
Wool, like a feather or down mattress topper, does tend to flatten and lose its shape, but usually just needs a shake or two to regain its shape. A wool topper is also not an option if you are looking for support.
A memory foam mattress topper is a great choice if you desire a memory foam mattress, but are short on the cash. Memory foam provides excellent support for your whole body and is an ideal choice for those suffering from back neck, or joint issues. It also will not transfer movement. Perfect for those with a restless partner or if you tend to toss and turn at night.
Like a feather or down topper, memory foam is available with hypo-allergenic options if you tend to experience allergies.
A down side that many experience with memory foam is overheating at night. Memory foam is not as breathable as other options and may cause you to feel overly warm. However, some brands do offer solutions to this problem and offer toppers that regulate body temperature. Memory foam is a durable material and should last a number of years, though after a long period of time it might start keeping pressure indentations and not regain its shape as quickly.
A latex foam topper is a great alternative for people who prefer natural fibers as opposed to the man-made memory foam toppers. Like a memory foam topper, latex molds to the shape of your body, which will help to minimize tossing and turning at night. Also, the foam does not transfer motion.
Latex is a known allergy resister, so it is perfect for those who have allergies. Another advantage of a latex topper is its breathable nature, allowing it to regulate body temperature.
However, this type of mattress topper is high-maintenance. Difficult to clean, it will also lose its elasticity after awhile of using it and you may find indents staying after you have left the bed. Although, this should not happen until after many years of use.
