Very comfortable mattress. It arrived in a box and the tracking kept me informed of the delivery progress. It expanded quickly. However, it is very heavy and both my husband and I are finding it difficult to make the bed in the morning. I’ve never had a mattress so heavy.
We bought a QS firm mattress and base, as well as a single firm mattress for my adult son. It was easy to instal and fun to watch the mattresses plump up as we unpacked them. We found the mattress very supportive, quite firm at first, most likely because we had become used to our old ones. Over the last month or so, we are still very happy, especially as our back pain has gone. We are used to the firmness now, in fact, love it and don't need to consider a mattress topper at all. Great product, highly recommended.
