We have a new memory foam mattress that we bought for our guest bedroom. It was my wife who selected it. It actually took her a while to decide which one to get but we already set a certain budget for the mattress alone. I am glad that she found a good deal (which she always does).
Upon checking about this type, we have found out that there is memory foam pet beds too. I guess this type of beds are very popular especially for those with back problems. I admit this bed is really good because if you toss around when you can't sleep you won't disturb your bed partner.
