Complaining of a hard mattress yet too stubborn to get a new one? Here's something that might chase all your hard mattress blues away without having to haul it out of your beds: a latex foam topper. This may be the best thing yet... aside from getting a new softer mattress that is. It's cheaper than getting a new mattress and provides better support because of the latex material. It helps to regulate temperature too because of its "breathing mechanism". You can also choose the hypoallergenic ones if you have a family member who is allergic to dust mites and synthetic materials.
I too would get these mattress toppers should I want to reinforce my old ones. Saves me money and effort in throwing the old one out too! :D
