Sleep Studio 3-Inch ViscO2 - Corner ShotThe ViscO2 3″ Ventilated Mattress Topper is the answer to getting proper rest and a good night’s sleep. This memory foam mattress offers proper ventilation and increased comfort. This is a great alternative to replacing a still functional mattress that may have lost its comfort level. No need to get rid of it, just enhance it with the 3.0” ViscO2. Your wallet will thank you for this decision later.

This foam is specially designed using a modern, revolutionary high-performance memory foam from Sleep Studio. Unlike many different memory foams available on the market today, the 3.0” ViscO2 actually encourages comfort and a cool feeling because it permits five times more air flow. You don’t have to worry about waking your partner and your partner doesn’t have to worry about waking you because the foam reduces motion transfer, so fidgety movements will not be noticed by the other sleeper.

It’s normal for mold, mildew, fungi and bacterial odors to form; however the foam is made to combat this problem in a natural way, using anti-microbial treatment. The 3.0” Visco comes in a range of sizes: California king, king, queen, full, twin XL and twin. It comes with a standard 2-yr limited warranty.

Un-boxing & Adding To The Bed

Here is a photo gallery of unboxing and installing this mattress topper. The instructions said that it would take 24 hours to decompress this topper and 48 to rid of the initial factory smell. It only took about 4 hours for this one to decompress and it didn’t really have any sort of a smell. We had it on the bed in less than 6 hours after receiving it.

And yes, this is memory foam after all, so we have to do it. Here is the obligatory “hand print on memory foam” shot.

I had this big plan to air it out in the garage for a couple days before installing it, but ours didn’t have the factory smell that many people mention with other similar memory foam toppers. We just decompressed it in the office room and were able to put it on the bed the same night we got it delivered.

Here is what it looks like up close, with a quick example of the density/softness:

The Reviews

The ViscO2 3″ Ventilated Mattress Topper was reviewed by 155 different customers. The feedback was quite positive. Many people that had never tried using a memory foam were quite pleased with the comfort and the better sleep they had gained. One user, had tried many different beds and mattresses because she had always sought something firm but comfortable. The topper is what she was looking for and it didn’t justify the price of investing in a new mattress. She had “fallen in Love” were her exact words. She admitted that she had experienced the most relaxing night without the need for wine or tea.

Many liked the fact that it provided the right amount of firmness. With some memory foams, it is just too soft and does not always have the right amount of foam density. If you try some other models, you may find that your body sinks straight to the floor. One user had gone into several stores and felt it for himself. What he noticed is that you actually get a better foam pad without having to invest a lot of money. Comfort is very different and personal for everyone. With this mattress, you will always feel invited to lie on it and at times even crave the comfort that you feel when you first try it.
