Which firmness should I pick?

Side sleepers usually do best with the soft or medium. Back and stomach sleepers tend to prefer the firm. Heavier sleepers should lean firmer for support.

Does it need a box spring?

No. It works on a platform bed, slatted frame or adjustable base. A solid or closely slatted base gives the foam the support it needs.

How long until it fully expands?

Most of the expansion happens within 24 hours. It can take up to 48 to 72 hours to reach full height, and cool rooms slow it down.

Is it good for couples?

Yes for motion isolation, since the foam absorbs movement. Edge support is the weak point, so couples who sleep near the edges may notice roll-off.

Can I use a heated blanket on it?

Memory foam softens with heat, so a heated blanket or a very warm room can make it feel plusher. Use a mattress protector and keep the room cool for a firmer feel.

How does it compare with a hybrid mattress?

It costs less and isolates motion better, but a hybrid adds coils for stronger edges and a bouncier feel. Choose this one if you want simple all-foam support.
