What owners single out
Review 7's concern about mattress narrowing after expansion aligns with review 3's observation of uneven firmness and material deterioration affecting long-term fit and support.
In their words
“Listen right: I truly haven't found one been in all my 30 plus years of life that hugs and comforts my body like this. My daughter, sister and one of my closest friends has napped in my bed and they all say "omg why is your bed this comfortable? I didn't even mean to sleep that long." This mattress is so awesome. I get way more rest than I intend every night.”
Lauren W. · verified purchase · nectarsleep.com
“Took about a full day to completely expand - once it did it expanded up but seemed to have shortened the "out". It's now about 2" narrower at the sides of the bed than it was. Removing a start for this reason - bc this was one of the reasons I bought this mattress in the first place - so that it would fit side to side with no weird gaps between mattress and frame .”
