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.
