I purchased a queen Oasis set, from Comfort King and was promised a lifetime comfort guarantee... I was very dissatisfied with the results. But since, I was given a guarantee, I was committed to by. What I originally wanted was a Tempur-pedic, but after speaking with them, I was informed that Tempur-pedic was the most returned bed in the industry. So, I went with the Oasis. I was unhappy from the get go, and requested to get my money back, after they said they could fix it and make it better, which didnt work. So finally I bought the ever so downgraded Tempur-pedic, and love it more than anything I have slept on. I will never buy from Comfort King, and will live to tell others not to buy there either.
