The previous owners had taken out the Select Comfort mattress that came with it - so the dealership put in a brand new standard quality innerspring mattress. We tried to put up with it as long as we could.
We used to have a Tempurpedic bed when we lived in our stick built house. We were very happy with it and it really helped us sleep better. Unfortunately, it was a king size and wouldn't fit in the motorhome - so it went into storage. We just couldn't stomach spending another $3,000 for our motorhome mattress even though we yearned for the sleep we got on the Tempurpedic.
So off I went - researching our options. I thought about going to mattress shops - but the prices are always so expensive. I even looked at Overstock.com to see what they had (knowing their shipping was reasonable). I finally found a mattress on Amazon that seemed like it would be a good fit. The reviews were good - the price was right (about $370) - and shipping was free!
It arrived within 2 days (I have the Amazon Prime shipping memebership) in a box that was about 2' x 2' x 3' big. It was a bit on the heavy site (about 80 pounds) - but fit easily in the narrow door of the motorhome and through the doorways going back to the bedroom. We decided to unpack it in the bedroom rather than outside because we thought it would be easier to remove the box than to try to get the big unpacked mattress through the door in the motorhome.
The mattress comes compressed and "folded" up inside the box. That scared me a bit - but as soon as you remove the packaging, it expands nicely and within about 4 hours you couldn't even tell it was ever packed up. The directions said to allow up to 72 hours before sleeping on it - but it looked ready after 4 hours so we went ahead and slept on it that night.
We opted to donate our old mattress to a charity (which had been covered with a high end mattress protector so it was basically still new) - but we could have also just listed it on a site like FreeCycle or Craigslist if we needed to get rid of it.
Our first impression was that it was easily as comfortable as our Tempurpedic was. It has now been a couple weeks and we're still in love. We both agree that it's as good as our Tempurpedic was - but at a fraction of the price.
