That is not a lot of coils. When considering a coil mattress, there are other factors as well, such as pocketed or Bonnell, single or double heat tempered, the gauge of the wire and how many turns the coils have. I would have to say I would recommend something a bit more durable or you run the risk of replacing it in just a few short years and it likely would not be supportive for long. If you are on a budget, you would do better with an all foam mattress. There are affordable ones out there.

But will cost more than the average consumer expects. Due to the higher price for a quality innerspring most retailers are pushing memory foam mattresses with built in profits from the manufacturers.
