Frequently Asked Questions
Can the mattress be placed on a normal metal bed frame or would I need box spring?
SweetNight mattresses can be used with all type of bed frames with or without box springs.
What is the maximum supported weight for the mattresses?
All of our SweetNight mattresses can support up to 551 Lbs.
Do I really need to wait for 72 hours before I can use mynew mattress?
You may start to using your new mattress after 6 hours. However, we do recommend the 72 hour of time so that the mattress is able to fully expand, and get rid of any new product odors, due to our manufacturing, compression and shipping methods.
Why is my mattress taking longer than 72 hours to expand? What can I do to speed up the expansion process?
There are a few reasons that could prolong the expansion process:
1. Low room temperature.
2. The mattress is high-density and thick.
3. The mattress was wrapped and rolled in the shipping box for an extended period.
And here are some tips to help your mattress expand faster:
1. Place the mattress on a flat surface and wait a few more days.
2. Warm the room to at least 20°C (68°F).
3. Roll on the mattress for 10–30 minutes.
4. Massage the corners and any flat or lumpy areas to encourage further inflation.
How long can I keep my mattress in a box?
The mattress can be stored in the box for one month. But we suggest opening it earlier to prevent any impact on the mattress's expansion.
Can I test the mattress before buying it?
Unfortunately no. At this time we are selling our bedroom products online only. However, we do have plans for a retail store in the near future so you would be able to test out our mattresses in store.
