I bought this as a single size mattress.It came on time,with no delivery issues.Well packed and not damaged.It sprung well into shape after being unpacked.The new mattress smell as described in reviews I read , was minimal. I selected this mattress as it had a cooling aspect about it. I'm going through the menopausal hot flushes and it does seem to work. I'm pleased with the mattress.I would by again.
