Saatva. Go the store on 14th Street first to check them out. Then buy online.

anyone have any softer recommendations?

I love my Saatva that I bought online.

Wayfair bed in a box medium firm.

I love the "bed in a box" options. We ended up going with purple for my sons room, as it was pretty affordable. One side of the mattress is firm and one is medium, so you can flip the mattress based on your preference. I'm not sure if they do boxsprings though.

Looking to buy a full sized mattress and box spring for my 13 year old son. Would prefer to order online - any recommendations? Would like to find something moderately priced. He doesn’t like very firm mattresses, prefers something on the softer side.
