When it comes to getting a good night’s rest, a high-quality mattress is only part of the story. From finding the right pillows to limiting screen time and other distractions before bed, there are a lot of other factors that go into getting those precious REM cycles. That also means that if you have a subpar mattress or one that you’ve held onto for a few too many years, there are several steps you can take to make up for it.
Take the mattress topper, for example — as the first point of contact for your body, the right mattress topper goes a long way in improving your mattress’ comfort. If you have a king-size mattress, a soft mattress topper can be a great investment.
King size mattress toppers, just like the mattresses themselves, come in a variety of materials. If you need something that conforms to your body, memory foam is the best option. However, even cooling gel memory foam retains heat, so it may not be ideal for hot sleepers. A cotton topper with down or a down alternative will give that plush hotel suite feeling, but it won’t be as supportive as memory foam. Since everyone has different needs, we’ve rounded up the best king-size soft mattress toppers out right now (and if you don’t have a king-size mattress, the options below are available in all of the other common sizes).
1. Zinus Green Tea Memory Foam Mattress Topper
Green tea doesn’t just refer to the color of this mattress topper — it’s actually infused with green tea extract and charcoal, which have natural odor and bacteria-fighting properties. The foam topper is 1.5 inches thick, but 3-inc and 4-ich varieties are also available if you require more support. The foam provides adequate joint support and conforms to your body. The topper is also Centi-PUR certified for quality.
Pros: Green tea and charcoal-infused to absorb moisture and dispel odors, making this a good option for sweaty sleepers. Centi-PUR certified foam.
Cons: 1.5-inch thickness is somewhat thin.

2. LEISURE TOWN King Mattress Pad Cover
If you prefer a more plush option, consider this king-size mattress topper from Leisuretown. The cover is made from cotton, providing the cooling benefits and softness of this natural fiber. The fill is made from a synthetic down alternative. The cover has diamond-patterned cells that help ensure an even distribution of fill for greater comfort. The bottom of the topper has a pocket that fits under the mattress to keep it in place.
Pros: Plush cotton cover with synthetic fill. Deep pocket holds the cover to the mattress without it moving.
Cons: Some may not find it as cooling as they’d like.

3. Tempur-Pedic 3-Inch Medium Firm Mattress Topper, King
Unlike some memory foam mattress toppers, this option from Tempur-Pedic comes with a cover that protects the foam. The topper is a substantial 3 inches thick, providing the conforming benefits of memory foam. If you’ve experienced a Tempur-Pedic mattress and enjoyed it, but don’t want to spend too much for an entire mattress, then this topper is a more economical alternative. This particular option is the “medium-firm” topper, so it’s best for those looking for support. The cover itself is machine washable
Pros: Supportive medium-firm memory foam. Comes with a machine-washable cover.
Cons: More expensive than other options.

4. oaskys King Mattress Pad Cover
This option has a cotton cover with a synthetic down fill, and the bottom of it has a sleeve that fits under the corners of the mattress for a more secure fit. The top of the cover has square quilted cells that help to provide an even amount of coverage throughout. The cover also has a rounded border that help act as edge support to make it easier getting in and out of bed. As an added bonus, the entire cover is machine washable.
Pros: Soft cotton cover, quilted design for plush feeling. Deep pocket keeps cover in place.
Cons: Thin material makes it more of a mattress pad than a proper topper.

5. LINENSPA Memory Foam Mattress Topper – King Size
This option from Linenspa is available in either 2-inch or 3-inch thick varieties, although we like the 3-inch option for the greater plushness it provides. The memory foam topper is infused with cooling gel beads, which are designed to reduce heat retention. The memory foam conforms to your body’s unique sleeping patterns and helps to evenly distribute weight.
Pros: Relieves pressure by conforming to your body. Features cooling gel beads.
Cons: Can lose its firmness over time.
