Foam doesn't hold up well when it gets wet. It starts getting crumbly and brittle. Think how a kitchen sponge gets after too many uses. There are a lot of air cells in memory foam. Water can get into those cells and mess up the structure. It's recommended to use a waterproof mattress protector over the mattress and any memory foam topper you might have. The warnings against getting the topper wet doesn't apply to just the washing machine. That also applies to perspiration, drinks, or any other "wet spots" that might occur. This will damage the memory foam. That's why you should use the protector and wash that. /reas...NASA -style Memory Foam.Sponge Memory Foam.Nonflammable Sponge Memory FoamGel Sponge Memory Foam NASA-style Memory FoamSponge Memory Foam Nonflammable Sponge Memory FoamGel Sponge Memory FoamMemory foam is a soft urethane foam engineered to spring back more slowly than regular foam allowing it to conform to things resting on it. There is a temperature component to the conforming property so it conforms better to warm surfaces.
There are numerous problems with washing the material. It is an open cell foam so all of the cells connect allowing the material to become saturated. Water, at 64 lbs/cu ft, inside this matrix can make it too heavy to pick up. I imagine the spin cycle on your washer could destroy the machine before it can remove enough moisture. Trying to remove it wet may also tear the foam. Any treatments that were applied to the foam will be reduced or removed. Should you make it through the wash the dry cycle can be equally destructive. If you have one of the gel foam pads the gel component can not stand up to high heat like the foam can. If you compromise the gel cells the comfort level of the foam can go down drastically.If,as you say, the pad has already absorbed enough to be verging on disgusting then you have nothing to lose in the attempt if you monitor your washer and are prepared to shut it off quickly. Some sort of wringer and the hanging it out might be a better choice than a dryer. As far as what else you can do, we have found that a thin high quality mattress cover can keep the topper relatively clean to increase its useful life.
Good luck and be sure to video. Memory foam has an open cell structure. When you wash it the water gets in to all the little holes and doesn't dry. It takes a long time for it to dry out and in the time it takes mold and other things can start growing.The foam is also likely to fall apart.Here is a link to a site that gives suggestions on how to clean memory foam without putting it in a machine. A foam toppers can be a great addition to an existing mattress under some conditions. Unfortunately, they are limited to a very specific benefit. Toppers are made of a number of different types of foam: standard polyurethane, latex, memory (the most common) or a combination of foams. Many people purchase toppers in an effort to get a few more years out of an aging mattress. This rarely works because the reason that mattress is failing is that the springs or other support system is broken down and saggy. A topper will not solve this problem; only one thing will: a new mattress. The problem that toppers excel at solving is hardness.
If the surface of the mattress applying too much pressur to eht skin and joints, the topper will increase pressure reduction. Density: Memory foam has a density rating in pounds. A higher number (weight) indicates the memory foam is more dense which will give you better conformability and longer durability. The weight of most memory foams ranges from less than three pounds to more than five pounds. Toppers are common made of foam with a density of between two and four pounds. Higher density foams cost more than lower ones. Less than two pounds is not going to be very effective and is, therefore, not recommended. Also, some imported foams include materials other than the petrochemicals used to make foam, clay for instance. The inclusions will contribute weight, but not quality of performance. Thickness: Toppers can be purchased in thicknesses ranging from less than an inch to four inches. Generally speaking, a topper less than two inches will compress so much that it becomes effectively useless.
Toppers more than four inches are usually not needed. Thicker, of course, is more expensive. If you need a topper thicker than four inches, you do not need a topper, you need a different mattress! A thickness of two to three inches is usually optimal. 3″ gel-infused ventilated memory foam, microfiber cover CoolChoice breathable mesh gusset, hypoallergenic, spot clean foam, machine wash cover, 5 year limited warranty, Made in USA 2″ memory foam, 7 zone multi-surface design, microfiber cover CoolChoice breathable mesh gusset, hypoallergenic, spot clean foam, machine wash cover, 3 year limited warranty, Made in USARv Mattress TopperMattress SpaXl Twin MattressMattress SizesMemory Foam Mattress TopperQueen MattressBest MattressTopper SpaTopper FullForwardI really want a nice/substantial memory foam mattress topper.
