Thanks for the feedack Pete. Can you recommend a good choice (basic to mid line) for our 4 year old son. He is currently in a toddler bed and he is ready for a normal bed. We are thinking of full since we have a headboard and footbaord for a full size. Also, you mentioned the simmons Black as a better option as compared to the Silhoutte Marseille. We are looking for something in medium firm and Plush (Queen Size). We have tried both Simmons and S&F and like both, but are open to other brands as we are looking for quality and durability. Also do any of these brands use organic materials? Lastly, if we order the a mattress and box, what is the typical transit/delivery time to southern CA? Thanks for the feedback, we are certainly ready to get some new beds for the family.
