Firmness

With its 3-inch thickness and 700 GSM fill weight, the Down Alternative Featherbed Mattress Topper may have greater cushioning than a thinner 1-2-inch one. That makes it one to consider if you are looking for the best plush mattress topper to help soften the feel of your current mattress. It may be less suitable for someone who wants a topper to help their mattress feel slightly firmer. Improving the mattress’s feel helps some people get better sleep.

Many Mattress Topper Sizes

Saatva’s Down Alternative Featherbed Mattress Topper is 3” thick and is available in all the popular sizes you would expect:

  • Twin: 38” x 75”
  • Twin XL: 38” x 80”
  • Full: 54” x 75”
  • Queen: 60” x 80”
  • King/Split: 76” x 80”
  • Cal King/Split: 72” x 84”

These sizes correspond to standard US mattress sizes. For example, a king size topper is designed for use on a king size mattress. Choosing the right size can help you get the best fit to maximize the topper’s features, especially using the built-in anchor straps.

Construction Review of Saatva’s Down Alternative Featherbed Mattress Topper

These construction details can help you make a more informed decision about whether it is the best soft mattress topper for you. Let’s start with the cover.

Soft Cotton Cover

The topper’s cover is made of percale cotton, which is known for having a comfy, lighter feel and excellent breathability. The high-quality cotton material has a 200 thread count for softness and better durability.

Super-Plush Fill Blend

The Saatva Featherbed Mattress Topper features ultra-plush fill made of a blend of down alternative and lyocell fibers. The down alternative fibers in the 3-inch fill offer luxurious comfort and softness, while the lyocell fibers draw moisture from the body to help keep the sleep surface dry and comfortable.

This topper’s generous 700 GSM (grams per square meter) fill weight indicates a higher density. That makes for a fluffier, thicker topper. While a higher GSM typically means a warmer topper, the ultra-breathable materials make it less likely to lead to overheating. Plus, the box quilting helps the fill evenly distribute for superior plushness.

Corner Bands to Stay Put

When adding the best plush mattress topper to your current mattress, it is much more likely to be comfy if it doesn’t shift. Thankfully, anchor bands at each corner help the Down Alternative Featherbed Mattress Topper stay in place.

Textile Certification

This Saatva topper is OEKO-TEX® Standard 100 certified. This certification is globally recognized and sets the benchmark for textiles, showing that it has been tested for several harmful substances.

Saatva’s Down Alternative Featherbed Mattress Topper: Pros and Any Drawbacks

Ultra-Soft Feel

The cotton cover and evenly distributed, fluffy fill blend combine to give this topper a super-soft, luxurious feel. The premium down alternative fill offers plush comfort, and the lyocell fibers have a soft, smooth feel. Percale cotton, which the cover is made of, feels gentle against the skin for many people. The topper is like sleeping on a cloud, per Saatva’s US website.

Those seeking a softer sleep surface, which may happen if your new or existing mattress feels slightly too firm, may find this topper improves comfort. That could help your body relax for better sleep quality.

Pressure Relief

Pressure points, such as the hips and shoulders, can accumulate stress during the night, especially for side sleepers. That can lead to stiffness in the morning. Adding a topper with extra-dense filling and a 3-inch thickness, like this down alternative one, may help by cushioning pressure points. Some sleepers find adding a plush comfort layer, like this Saatva best soft mattress topper, helps with pressure relief while retaining the support of the mattress beneath.

Cooling and Breathable

While you might assume that the thick filling sleeps warm, the Down Alternative Featherbed Mattress Topper is constructed to reduce the likelihood of that. The lyocell fibers are naturally breathable and moisture-wicking, drawing heat from the body. Those who sleep hot may find relief, especially with the addition of the airy cotton cover. During warm months, the lyocell may help with cooler sleep.

Not American Made

This Saatva topper is manufactured in India, per Saatva’s custom service (via its US site’s online chat feature). While not made in the US, which some people look for, it has premium materials and the potential to improve the sleeping environment of certain people. Those qualities may be more important for certain shoppers. Plus, this plush mattress topper ships within the continental US for free.

Side Sleepers

The plush feel of the Down Alternative Featherbed Topper is most likely to benefit side sleepers, but less so for other sleep positions. Stomach sleepers do not typically choose soft mattress toppers as their midsection may sink too far, leading to discomfort. Some back sleepers may prefer a thinner topper to maintain spinal alignment.

Animal-Free

Choosing an animal-free topper may be important to you. The Featherbed Topper offers the softness of down without using real feathers plucked from ducks or geese. Lyocell fibers are made from wood pulp.

Hypoallergenic

This Saatva topper features hypoallergenic down alternative fill. That reduces exposure to allergens like dust mites and mold while sleeping, potentially preventing waking up sneezing or with other allergy-related symptoms. The lyocell fibers may suit some people with sensitive skin who find the smooth feel reduces the likelihood of irritation or itch.

Machine Washable

Being able to put the Down Alternative Featherbed Topper in the washing machine is a great benefit. The best care is to wash the topper on a gentle cold-water cycle, no bleach, and tumble dry low, as per Saatva’s US site. Machine washing is convenient, making cleaning the topper easier, as part of maintaining a hygienic sleep environment.

What about Value? Assessing the Best Soft Mattress Topper

This luxurious Featherbed Topper is at the higher end of the soft mattress toppers price range. While it is not the cheapest, it is excellent value for the premium construction, in our opinion. The down alternative and lyocell fiber fill blend and cotton cover are durable materials that can help the topper last longer and maintain its shape with proper care.

Plus, the use of down alternative rather than down keeps this topper more affordable, without sacrificing ultra-plush comfort. A quality topper can also help your existing mattress feel more comfortable at a much lower price than purchasing a new mattress.

Adding to the topper’s value is Saatva’s free ground shipping within the continental US. It ships conveniently to your home, saving having to pick it up yourself.

Also valuable is the lengthy 180-night sleep trial that comes with this Saatva topper. This period gives you several nights to get used to the topper at home. In the rare instance you’re not completely satisfied, being able to return it for a full refund with free return shipping can be reassuring.

The warranty adds further protection. Saatva includes a 1-year limited warranty against workmanship defects with the Down Alternative Featherbed Topper. The related policy covers what is included, exclusions, and more about what to expect regarding repair and replacement.

Saatva Down Alternative Featherbed Mattress Topper Review: Conclusion

Finding machine-washable soft mattress toppers with premium materials and top-quality construction online may seem impossible. Yet that’s precisely what this Saatva Down Alternative Topper offers. The 3-inch-thick accessory is designed to improve the softness of the sleep surface with an ultra-plush feel while retaining the support of the mattress beneath it. That may lead to greater comfort, potentially helping improve sleep, especially for side sleepers looking for pressure relief.

While stomach and back sleepers may not have enough support with this topper, some hot sleepers may enjoy a comfier experience by adding it. A cooler sleep is possible with the topper’s airy percale cotton cover and highly breathable filling that includes moisture-wicking lyocell fibers. The topper also likely appeals to those who want a quality-made hypoallergenic or animal-free topper.

Finally, Saatva’s included warranty and long 180-night sleep trial enhance its value. For those who want to soften the feel of a mattress that feels slightly too firm and enjoy a luxurious sleep experience, the Down Alternative Featherbed Mattress Topper is one to consider.
