The rule of thumb in buying Memory Foam:

• Memory foams are priced differently but the range of prices should fall between $2000 to $3000. Toppers are about $200 to $400. With memory foams, quality is already assured but it doesn’t mean that the higher the price of the memory foam is, the better it is from other brands. At $2300, you can have a good memory foam mattress.
• Memory foams come in different levels of thickness. You can opt for the thickest type but then you may go way over budget with it, or you may not have enough mattress support from your bed’s frame. Deciding on how thick should the mattress be is also dependent on your personal choice. But to be safe, get a memory foam that is suited for your bedroom or bed frame.
• Getting a memory foam topper is an option. But really, what its good for is reducing and protecting your memory foam from wear and tear, making it last longer.
