I Tested the Saatva Micro-Coil Mattress Topper − It's Very Soft and Comfortable, But Lacks Edge Support and Motion Isolation

The older I get, the more important I realize that sleep is. I’ve previously tested mattresses for Homes & Gardens that I continue to use, and wondered if a great mattress could be made even better with a mattress topper, like the Saatva Micro-Coil Mattress Topper. That's why I was excited to test it out.

I used the King-sized topper for a little over a month, so I could get a sense of how it would impact my sleep, testing it for support, comfort, and motion isolation. While this mattress lacks motion isolation, I think it would be a great addition for someone who wants to make their current mattress even more comfortable.

Here, I detail my findings after testing this mattress topper for over 30 days, and explain if it’s something that would earn a permanent home on my bed.

The Saatva Micro-Coil Mattress Topper: Specifications

The Saatva Micro-Coil Mattress Topper: Delivery, Unboxing, and Set-Up

The Saatva Micro-Coil Mattress Topper arrived at my doorstep in a large cardboard box, rolled up and wrapped in a layer of plastic. I was able to carry the box by myself to the third floor of my home, cut off the plastic, and immediately added it to my bed. I didn’t need to wait for the mattress to inflate, and there was no odor or off-gassing at all.

The mattress topper has elastic bands on all four corners, so it was easy to put it on top of our mattress, secure it, and cover it with a fitted sheet with minimal wrinkles or effort. I could immediately see and feel the three inches of height from the mattress topper, which was especially noticeable at first but became normal after about two weeks. From there, it was simply a matter of assessing what it would be like to sleep on.

What’s it Like to Sleep on the Saatva Micro-Coil Mattress Topper?

Pressure relief (4/5): The Saatva Micro-Coil Mattress Topper excels when it comes to the quality of materials, and the body-contouring foam and organic cotton make the mattress topper very soft to lie on. I couldn’t feel any of the micro-coils through the mattress, but this construction offered support while sleeping.

Thermoregulation (4/5): While the mattress isn’t specifically marketed as thermoregulating, I found that it didn’t get too hot when I slept in one area, which was great for the warmer days in fall.

Motion Isolation (3/5): While my Layla Hybrid Mattress on its own has great motion isolation, that felt less true with the Saatva Micro-Coil Mattress Topper. I tested this by placing a cup of water in the middle of the bare mattress topper and applied pressure around it. The water in the cup sloshed around noticeably when pressure was applied elsewhere on the topper, indicating some motion transfer. Notably, the cup stayed upright every time we tested this except once, when it completely fell over.

Edge support (2/5): This mattress topper is designed with a one-inch recycled steel micro-coil layer that’s reinforced in the center third and perimeter of the topper for enhanced lumbar and edge support, but I found that the edges compressed significantly when I sat on it. My spouse reported the same issue and said she felt as though she was sliding off whenever she sat on the side of the bed to put on her socks. I could also feel when my spouse got in and out of bed and vice versa.

I also put a 5-and a 10-pound weight in the middle of the mattress, and both sank very minimally, which suggests that the middle is more supportive than the edges.

Who would the Saatva Micro-Coil Mattress Topper Suit?

While the Saatva Micro-Coil Mattress Topper is not designed with a specific sleeping position in mind, it may be ideal for someone who’s looking for a softer mattress and is either trying to extend the life of their current mattress, fix a sagging mattress, or make their current mattress a little less firm.

It may also be a good choice for someone who would appreciate the use of materials that are better for the environment, like the recycled steel micro-coils and organic cotton blend cover. It’s also made with CertiPUR-US certified foam, which means that it’s free of formaldehyde, ozone depleters, and phthalates regulated by the U.S. Consumer Product Safety Commission.

Because the motion isolation was not as great as expected, this mattress topper may be better suited for someone who doesn’t share a mattress, or people who aren’t light sleepers and wouldn’t wake up from the motion of someone else getting out of bed.

What Do Shoppers Say About The Micro-Coil Mattress Topper?

On Saatva’s site, the Micro-Coil Mattress Topper has an average rating of 4.7 stars across 305 reviews. People like it for its comfort and having the right amount of cushion, and many reviewers note that they wake up in less pain.

'Game changer,' says Kimberly, for example. 'I was looking for relief from my hip pain that kept me up at night and was going to buy a whole new mattress set then I came across this topper and it is for sure the best purchase of the year for me!

'I'm sleeping comfortably for the first time in months without taking ibuprofen before bed. It is so comfortable! Definitely worth it!'

Some lower-rated reviewers note that the mattress topper gets hot easily or that it slips around on their mattress, but otherwise, they mostly note a preference for a firmer mattress.

My Verdict

This mattress topper is a great option for someone who wants a mattress made with environmentally conscious materials and delivers support, though I wish it had better edge support and motion isolation.
