What Topper over 10" Memory Foam Mattress

My wife and I bought a 10" Memory Foam Mattress from Overstock.Com two weeks ago, and I'm finding it too soft for me.  I'm 6.4 and 220lbs and I find the 3 inches of 5lb Memory Foam is too soft and it feels like my pressure points on my back and sides sink in all the way to the 7 inch layer of foam on the bottom.  Some mornings I have some light lower back pain, and wish the mattress had a bit more support.  Is there anything I can do about this?  Overstock doesn't take mattress returns, so that's not an option. 

Would it make sense to buy a Topper, and if so I'd be grateful for recommendations.  Should I go with a latex topper on top of the memory foam?  And what thickness would work well?

Thanks.

Kbell,

Overstock describes the mattress combination this way: "Incredible mattress features a 3-inch layer of 5-pound density Nasa developed memory foam on top of a 7-inch, 2.5-pound density supportive base layer of traditional foam"

What would happen if I put a 1" layer of firm latex between the 3" layer of memory foam and the base layer?  Would that add more support?

Can you actually separate the layers? Most mattresses bond the two foams together. If you can separate the layers you might be better off putting some 44 ILD HR foam under the visco. You're a big guy and need something extra firm to give you more support. Overstock's description doesn't specify what ILD the base foam is. It might be 35--which is firm, just not firm enough for someone your weight. You could try this in 1" increments. If it's still too soft try adding another inch. Placing firmer foam under the visco will make the MF feel firmer too. But it doesn't work the other way. You have to place the support foam under the visco not over it.

Algreen - If the problem is due to a lack of support provided by the foundation layer then I doubt your solution would work out in the long run. However I went to the Overstock.com website and read some of the bad reviews. You will see many good reviews although I did not see any that said they had the mattress for several months. Most of the people who left bad reviews felt the mattress was too firm (although not all did.) If the problem is that you're sinking through a comfort layer into a too firm foundation layer and that is what is creating the pressure points then an additional intermediate layer may solve the problem for you. From the review by bedanalyzer, "This top three inches are way squishier than I was expecting and the bottom way firmer."

The point of a third layer in a three layer foam mattress is exactly this; to make a smooth transition between the comfort layer to the foundation layer. The problem with this approach is that if the memory foam really is too soft then adding an intermediate layer may increase the chances of hammocking. One of the reviewers mentioned that the layers were bonded so you'll need to check that out. In the final analysis though if the foams used in this mattress are not high quality (which is fairly likely at this price point) then any attempt to fix the problem may be a bandaid solution. You could be throwing good money after bad.

Cloud9 - Thanks for straightening me out on Overstock's new return policy. For me it isn't long enough and I'll take my money elsewhere.
