We love this Serta Elite Extra Firm Mattress! Super firm just as it claims, and very well constructed. We sleep great now! But be aware, it's extra firm just like it says. Wayfair's delivery was right on time and we were even able to get our old mattress hauled away for a fair price. The dump would have charged us way more, plus we didn't have to haul it there! Such a huge convenience and great experience all around! Once again, thank you WAYFAIR!!
