Viscosoft Serene Hybrid Mattress Topper review

Okay, I admit it: I was on a tight timeframe when moving into my apartment and I bought a bed-in-a-box. While convenient in its delivery and self-transport, it did not meet my comfort expectations. At only 8 inches in height with steel coils, the mattress was too firm for me. In retrospect, I realized the product details did say that the mattress was ideal for stomach and back sleepers. And I am, you guessed it, a side sleeper. So as soon as I realized my mistake, my search for a mattress topper accelerated. 

I knew I needed more comfort to avoid waking up with shoulder pain from sleeping on my side, and the Viscosoft Serene Hybrid Mattress Topper appealed to me for its dual design, promising superior comfort through the combination of memory foam and a separate pillow-top cover.

The Viscosoft Serene Hybrid Mattress Topper has a memory foam base made out of CertiPUR-US gel-infused memory foam that is combined with a down-alternative pillow-top cover. It is available in a three or four-inch option. I tested the four-inch which adds additional softness and is highly recommended for those looking for additional cushion. This consists of 2.5 inches of memory foam and 1.5 inches of the down-alternative cover, while the three-inch is half gel foam. As for the pillow-top cover, this is machine-washable and easy to install over a mattress and mattress topper with its four built-in corner elastic straps. Inside, the quilted design has a plush 700gsm down alternative fill with a 300-thread count cotton cover.

TLDR: What I thought of the ViscoSoft Serene Hybrid mattress topper

Before I received the Viscosoft Serene Hybrid Mattress Topper, I was contemplating replacing my bed-in-a-box with a more plush, traditional mattress. Of course, while I was looking at a new mattress, a significant consideration was the cost of a new one.

This mattress topper caters to all sleepers, including back, stomach, and side sleepers. It is soft enough for side sleepers and also has enough support to satisfy both back and stomach sleepers. 

While a good portion of my review is subjective, I can confidently say that this mattress topper exceeded my expectations. I would recommend it to anyone looking for an affordable option to add significant softness to a firm mattress. It improved my bed-in-a-box significantly and took its firmness level from a 9 (with 10 being the most firm) to a 5. With my budget intact and my new mattress topper in place, I won’t lose any more sleep over my bed-in-a-box.

Unboxing the the Viscosoft Serene Hybrid Mattress Topper

The Serene Hybrid Mattress Topper is available to order through Viscosoft’s website, as well as through Amazon. Viscosoft offers free shipping for its Serene Hybrid Mattress Topper and advertises a typical product delivery time of three business days. The length of time from my order confirmation email to my mattress topper delivery was five business days. I received an email from Viscosoft that included a correctly estimated delivery date and UPS tracking number. I also received additional emails with delivery status updates. 

When my full-sized (75” x 54” x 4”) mattress topper was delivered, I was surprised at how small the box was. I carried the box from my building’s package delivery room to my apartment unit with the help of my roommate. I thought it would be too heavy to carry myself; however, I would have been able to carry it up to my apartment without needing assistance. 

Once opened, the box contained a cylindrical-shaped package, which was the tightly compressed memory foam base wrapped in plastic. There was also a briefcase-style package made out of a sturdy fabric material that contained the down-alternative pillow top cover. The pillow top cover within the briefcase was also wrapped in plastic. 

After removing the plastic binding, the memory foam immediately expanded and began airing out. It does emit that strong new memory foam smell. Viscosoft recommends letting the foam air out for at least 24 hours, so I left the mattress flat in my living room and flipped it over halfway during the 24-hour period. The odor did dissipate significantly after the 24-hour period, but the remaining memory foam smell lingered noticeably for a little over a week, though not at a level that bothered me. I could easily carry the memory foam base to my mattress and set it up myself, complete with the down-alternative pillow top cover. 

The cover was easy to install over the topper and my mattress, like a fitted sheet, with its elastic straps and deep 18” skirt. While the tight elastic straps from the cover made dents at the corners of the mattress topper, they did not affect its use. The dents were not visible once my comforter was in place, and the dents eventually leveled out over the course of the first month.

Is the Viscosoft Serene Hybrid Mattress Topper comfortable?

For the first night with my mattress topper, the new memory foam smell was most prevalent, but that was my only complaint. I had a more restful night's sleep than I had in a while and no joint pain from sleeping on my side.

The new memory foam smell did last noticeably a little over a week, but not to a level that bothered me.  

Comfort, Firmness, and Support
My basic bed-in-a-box mattress went from a 9 on a 1–10 firmness scale (with 10 being the most firm) to a 5. My body adjusted immediately to the new mattress, and the memory foam continued to retain its shape after each night. 

While I am not a back or stomach sleeper, I believe the mattress topper is supportive enough to accommodate all sleep positions. I typically sleep in the middle of my bed, and I didn’t find myself sinking uncomfortably into the mattress as a woman of average height and build. The mattress topper has continued to retain its shape without any indentations. I have struggled with lower back stiffness from time to time due to an old injury, and I still felt well-supported while sleeping on my side. 

I do feel the need to note that I used this mattress topper with a very firm mattress underneath. So, those with a mattress that is already too soft might find the additional mattress topper to have too much cushion when paired with the softer mattress.

Motion Isolation
This mattress topper performed well when balancing a cup of water on various areas of the mattress. Even with the plush-down-alternative cover installed, the middle, edges, and sides of the mattress topper were all able to hold the cup, and the mattress topper immediately regained its shape whenever the glass of water was lifted. Similarly, I’d expect the mattress topper to limit movement when sharing the bed with a partner. 

Is the Viscosoft Serene Hybrid Mattress Topper breathable and cool?

While I would not go as far as to say the Viscosoft Serene Hybrid Mattress Topper traps heat, I did notice it was slightly warmer than sleeping without it on my bed in a box. The slight additional heat did not affect my sleep.

If you are worried about overheating in your sleep, I would still recommend trying this mattress topper because I did not find it to be warmer to the point of discomfort. If you're naturally a hot sleeper or your room tends to be super warm in the summer, you might want to avoid this topper.

Real Homes' Review Process

There's much more to how we test mattresses (and toppers) ICYWW, but for a brief overview, our mattress topper testers are all required to sleep on their bed with the new product for a minimum of three to four weeks before reaching their verdict, testing the topper according to a strict brief. This allows Real Homes to compare and contrast their mattress topper experiences to find the best product. During the review, we will pay close attention to comfort, support, cost, and how it lives up to claims. We will also choose a reviewer depending on how they sleep, and we will ensure that this matches the type of topper we give them.
