How long does the mattress take to expand?

Hi, I will be getting an R1 mattress delivered on Monday, and I was wondering how long I should wait to use the mattress? How long does it take to expand?
Asked by: Jacquie
Let the mattress air out for 24-36 hours and to expand fully and then it’s good to use.

What does the R1 (and R2) Firm Eastern King Mattress weigh and what support is needed underneath?

The R1 (and R2) Firm Eastern King Mattress weight matters to me since I have a big/heavy bed frame. I need something fairly light so that the floor of the Victorian where I live (3nd floor) is not further stressed. Also, what type of support is needed under the mattress? I only have partial wood planks/boards placed over three metal support rails, so will the mattress require a full flat support underneath?

When using a board bed frame defiantly go with a low profile box spring unless you want a super high bed

R1 FIRM TWIN EXTRA LONG MATTRESS is rated 4.6 out of 5 by 43.
Rated 5 out of 5 by from Super Comfortable I was a bit skeptical when this mattress was delivered rolled up. But after installing it and giving it a day to expand, this bed had proven to be a great purchase. It's super comfortable. I highly recommend it.

Rated 4 out of 5 by from A little disappointed The sales representative told us the mattress was 12 inches deep; not so..... it is barely 10 inches. However the mattress we looked at in the store was definitely deeper than 10 inches. Bait and switch? Also, we were definitely not told about the strong odor the mattress would emit upon removal from the box. It has since disappeared, but it was definitely awful. The mattress IS comfortable, but anyone buying it should be aware of these hitches.

Rated 4 out of 5 by from Mattress Overall good quality but firmer than the test mattresses in the store. Much firmer. Would have gone with medium instead of firm if I had known.
