SweetNight sells mattresses, toppers, bedding and adjustable bases direct in the US. Same imported-mattress segment as Zinus.
Shipping
United States only. The policy says it plainly and does not pretend otherwise — no regional storefronts, no "most countries". Remote regions may carry an extra fee depending on distance from the fulfilment centre.
Clean limitation, honestly stated.
Returns: two windows inside one
The mattress policy is a hundred-night trial, but it is structured:
Unopened, return within thirty days of delivery for a full refund. Opened, there is a mandatory thirty-night adjustment period before a return can be made at all. After that, returns are accepted within a hundred days of delivery.
So the real window for a mattress you have slept on is night thirty to night one hundred. About ten weeks, not fourteen.
Condition requirements are strict: sanitary, donatable, free of stains, tears or excessive wear. Toppers follow a similar structure over thirty days.
Why the minimum exists
Mattress companies impose it because otherwise everyone returns in week one, before their body has adapted, and the guarantee becomes unaffordable. Thirty nights is a reasonable adaptation period. It is also a restriction, and it means the guarantee is not "return it any time in the next hundred nights" but "live with it for a month, then decide".
If you are moving house or changing your sleep setup inside that month, plan around it.
The condition bar is the practical risk. A mattress protector is not optional here — one spill and the trial is gone.
How it compares
Zinus offers the same hundred-night headline without the mandatory adjustment period, and with thirty days on furniture as well. SweetNight's mandatory thirty nights is the differentiator, and it cuts both ways: it protects you from a hasty decision and it stops you making one.
If you want the ability to return in week two, Zinus is the better set of terms. If you intend to sleep on it for a month before deciding anyway, the two are close, and SweetNight's stricter condition wording is what to watch.
Who it is for
US buyers who understand they are committing to thirty nights. Not for anyone expecting to return in the first month, and not for anyone who will skip the protector.
