Do not use ever.
This company plays on the concept you are getting a great mattress for a good deal. This is not true. The sales people want to make you feel like Sears, RC Willey, etc... are just trying to rip you off when they are the deceiving ones. Their mattesses are not comfortable and watch the quality you receive. I purchased a better quality mattress from Sears for a better price. I would prefer to sleep on the ground then deal with these guys again.
