My wife and I replaced a 25 year old queen sized Sealy Posturpedic mattress with two Serta Perfect Sleeper Plush Twin XL mattresses and two Serta Motion Essentials adjustable foundations. I did a lot of research before purchasing but ultimately made a decision based on price. We've been sleeping on the mattresses for about a 45 days now and really like both the mattresses and the foundations. We've never had adjustable foundations before but really like them for reading and watching tv. So far, we have no complaints about the mattresses or the foundations.
