Manufactured by Sleep Studios, this ViscO2 ventilated mattress enhancer brings the comfortof memory foam to your standard bed. A full two inches of high performance memory foamprovide soft comfort, while supporting an aching back and joints. With memory foam, thethicker and denser the foam is, the greater the support it provides. The ViscO2 ventilatedmattress enhancer has a 3-pound density, giving it a moderate support threshold and weightredistribution.

Many people use mattress toppers to get a longer life out of their mattress. Springs and othermattress materials can weaken and become depressed over time, leading to sagging anddiscomfort. Toppers redistribute your weight across the surface of the mattress, leading toless pressure on the areas you lay on. If you’re looking for a cheap way to extend the life ofyour aging mattress, this ViscO2 ventilated mattress enhancer provides a great way to do it.

This memory foam mattress topper includes many of the features you want to see in a qualitymattress topper. Memory foam can become warm without ventilation, leading to sweaty anduncomfortable sleep. The ViscO2 ventilated mattress enhancer uses a special ventilateddesign, which lets air circulate through the topper to keep it cool. Air channels are runthrough the topper, in addition to the normal ventilation “holes” found in competing products.This is where the “ViscO2” in the topper’s name comes from, referring to the periodic namefor oxygen. This topper is also naturally hypo-allergenic, and fights off fungi, mildew, moldand odor using a process called MicroSafe.

Though the ViscO2 ventilated mattress enhancer has a nice design and quality features,there are still some things to think about before you buy. For one, the topper doesn’t matchup properly with the ends of a standard bed. Though it comes in every size (including TwinXL and California King), there is a gap between the edge of the topper and the end of thebed. This extra space can make the topper slide around between the sheet and the mattress,so adding an extra fitted sheet between the mattress and topper can help it stick better.

Also, the memory foam itself is a bit of the drawback on this mattress topper. This foam is ofa somewhat lower grade than what’s found on higher-end memory foam mattress toppers,which will show over time. This, coupled with the relatively low density and thickness, cancontribute to a short shelf life for this mattress topper. You could wind up needing to replacethis topper twice before a high-quality alternative would need replacement, nullifying thesavings you’d get from buying this cheaper option. So while it’s great for extending mattresslife or providing a little relief, the ViscO2 ventilated mattress enhancer is definitely notthe “Holy Grail” of mattress toppers.
