My sister had suggested that I buy a Serta mattress as my old mattress was old and too firm. I am so glad she did! I purchased the Kleimon II Pillow Top Plush, and it is so comfortable! I find that I can't wait to go to bed! It has a perfect blend and feel of sleeping on clouds with great support! I am now sleeping peacefully through the night! Thank you so much, Serta for this great mattress!
