I bought two of these and you did not require the Serial numbers

I feel I've been getting a better night's sleep and my back doesn't seem to hurt.

I'll get a full night's sleep in this bed.It's great

So far very comfortable, a new type of comfort for me

Comfy and supportive but pillow top wore out quick

Medium firmness,comfortable.

Only had a week but hope it doesn’t sag too soon

Very comfortable. Best night sleep in years.

Comfy and supportive my dog and I like it

Excited for my second Serta mattress after 10 years
