Very comfortable bed and I love the 5 chambers for each sleeper as well as the potential to replace parts down the road versus the whole bed. Both my husband and I are athletic people but both of us have lower back issues so this bed is a great solution to a long standing problem of beds that wear out unreasonably fast and aggravate our sciatica. My previous bed was less than 2 years old and I was waking up in serious pain – the ReST bed helped resolve and prevent further issues. The bed itself is high quality but the customer service is stellar – extremely responsive to questions/issues and called to check on our satisfaction with delivery and with the bed itself. Highly recommend!
