The Mattress Nerd’s Take: The Viscosoft Select High Density Mattress Topper is the company’s most popular mattress topper. This model comes in multiple firmness options, is soft-to-the-touch, breathable, and supportive. Plus, it’s hot sleeper friendly thanks to the bamboo rayon cover and the cooling gel memory foam insert. Back and side sleepers will love it most, but it won’t be the best option for stomach sleepers.  

Who It’s Good For

  • Hot Sleepers
  • Back Sleepers
  • Side Sleepers
  • Those looking for a supportive , medium-firm topper

Who It’s Not Good For

  • Traditional memory foam lovers
  • Stomach Sleepers
  • Budget Shoppers

What is the Viscosoft Select High Density Mattress Topper Made Of?

Bamboo Rayon Cover

The Viscosoft topper’s bamboo rayon cover has a soft, stretchy feel and aids the topper’s breathability. The cover is also removable and machine-washable, making it a good choice for people who pay careful attention to their bedding products’ cleanliness and overall sleep hygiene. The cover features elastic straps at each corner to discourage sliding and to encourage a secure fit.

Cooling Gel-Infused Memory Foam

This breathable 3″/4″ layer of gel-infused memory foam is engineered to optimize air flow and minimize trapped body heat. It has a high-density feel than is much more supportive than most memory foam toppers, giving it a medium-firm feel that’s best-suited to average-weight and heavyweight back and side sleepers.

You might be asking— what the heck does “high density foam” really mean? It’s just a fancy way of saying this foam has a high weight per cubic foot, so there’s just more foam than air, making it very durable.

What Does the Viscosoft Select High Density Mattress Topper Feel Like?

I took the Viscosoft Select High Density mattress topper home and tried it out for myself. The foam felt plush, yet supportive at the same time, which kept me elevated on top of the surface, while still getting cushioned by the foams all around my body. I definitely noticed that the longer I laid on the surface,  the further I sank into the foam. So the foam is definitely slow responding and gives to the weight of your body as time passes.

I tested this topper out on a firm mattress, about an 8 out of 10 on our firmness scale, and by adding the topper, I’d say the firmness is now at about a 6.5 out of 10, making it a good bit softer than it was before. I’d say if you experience lower back pain or neck pain, the high-density foam will provide you great relief in those areas. The foam will contour to your body’s curves and make you feel relaxed, without giving an engulfing sensation. 



  • Its firm feel makes it more durable than other toppers
  • Hot sleepers will benefit from the breathable, bamboo rayon cover and gel-infused foam
  • Despite being a Medium Firm topper, it conforms to the body moderately
  • Provides excellent motion isolation, making it great for couples
  • Available at, Amazon and other third-party retailers


  • Not best for stomach sleepers
  • The foam tends to emit an odor, called “off-gassing,” upon unpacking
  • Pricey

Warranty Coverage

Why would someone purchase a dense mattress topper from ViscoSoft?

While most mattress toppers are purchased by sleepers who want to soften the feel of their mattress, some sleepers want to make their bed more comfortable but not softer. This dense topper is ideal for back and stomach sleepers who need a firm, even sleeping surface but also seek contouring abilities and added cooling in a topper.

Can this topper be used with a mattress pad?

Yes, you can layer any thin mattress pad on top of your new mattress topper to protect it and your mattress from spills and stains. Just place a fitted sheet over both products. Keep in mind that, depending on the pad, it may change the feel, firmness and comfort level of the topper.

The Nerd’s Final Take

The Viscosoft Select High Density mattress topper is ideal for people who want to improve the feel of an old mattress but don’t want a topper that’s too soft. The high density gel memory foam used in its construction makes it an ideal top layer for people who want relief for pressure points in the back and side sleeping positions but prefer the feel of a firm, supportive mattress. This topper will also be great for hot sleepers looking for an option that uses cooling materials like bamboo rayon, and gel memory foam. 

If your body weight is less than 130 pounds, especially if you’re a side sleeper, this may not be the best mattress topper for you because we did notice slight pressure build up in the shoulders. And if you sleep on your stomach, this topper will still be too soft for your sleeping position, since stomach sleepers require a firm sleeping surface that elevates their hips. Still, Viscosoft also offers this topper in charcoal and lavender infused options, which come with their own additional features.
