Choose a ViscoSoft High Density mattressThe high-density ViscoSoft mattress of your choice uses memory foam that molds to your body to reduce stress on your joints. Gel injections and micro-holes are designed to reduce heat build-up and keep the top cooler than many other foam models. Customers can also add refreshing charcoal or calming lavender to their memory foam. The cover is made of bamboo silk, a breathable material that regulates the temperature of the surface. The mesh under the cover provides more airflow and the elastic straps ensure that you can attach the cover to the mattress. The cover is completely removable and machine washable for easy maintenance. The upper has a medium texture (5) that balances cushioning and support and attracts a variety of games. Buyers can choose between 2-inch and 3-inch options. Both options are equally soft, but the thicker model changes the feel of the mattress significantly. Our testers chose the top for side blocks weighing up to 230 pounds and rear blocks under 130 pounds. The thick memory foam frame significantly reduces pressure on your hips and shoulders, while the moderate stiffness gives you enough support to align your spine. The foam layer also perfectly absorbs movement and sound, which is great for couples who often suffer from their partners on the road at night. ViscoSoft offers buyers a 90-night trial to try out the mattress. Some high-density mattresses come with a 5-year warranty and are shipped by the company to customers in the neighboring United States.

Sleepyhead Gel Topper can greatly help students with mattress problems. Those looking for a Twin XL cover can choose between 2-inch and 3-inch profiles. The latter is best suited for frequently used mattresses, while the shorter model provides a noticeable comfort fit for mattresses with some wear and tear.

The foam is laminated with a breathable polyester cover for greater temperature control.

- Organic snow silk mattress cover
If your mattress looks bumpy or uneven on the surface, it's likely that you're increasing pressure on your shoulders, back, or hips. A mattress topper can be a temporary solution to this problem, as long as it provides even support. The organic silk and snow mattress contains Dunlop latex, a dense, durable material that resists sagging and punctures better than foam. Latex is also naturally responsive, so the top layer bounces off a bit when you go to bed, allowing you to move across the surface with ease. 
Two hardness levels are available for the top. The medium feel (5) provides precise definition and cushioning, making this firmness option best suited for side sleepers. People who mostly sleep on their sides can benefit from extra padding for the shoulders and hips. If you sleep on your back or stomach, a firm feel (7) may be more comfortable - these postures often require more support around your stomach. Both designs are 2" thick. The cover is made of organic cotton which is breathable and the latex doesn't absorb much heat, so the topper is a good choice for warm sleepers. Environmentally conscious individuals should also find the top layer attractive, as the cotton and latex are certified to the Global Organic Textile Standard and the Global Organic Latex Standard, respectively. These credentials ensure that materials are evaluated for sustainable sourcing and production using rigorous standards. You can remove the cover and wash it in your appliances, but latex should only be cleaned when necessary.
