Which is better for an adjustable bed?

The Isabella. It is explicitly listed as adjustable-bed compatible, and its 14-inch build flexes with the base. The SweetNight does not list adjustable-bed support.

The SweetNight. Its gel memory foam is designed for temperature regulation, while the Isabella uses standard foams and an innerspring core with no cooling layer.

Neither maker publishes a durability rating. The Isabella's thicker build and the SweetNight's coil-plus-foam core both target medium-firm support, but the SweetNight has a 4.5-star rating from 97 buyers as a track record the Isabella lacks.

Is the Isabella worth the extra over the SweetNight?

It depends on the size and the day. The Isabella has ranged from $182 to $248 in the past week. At the low end it is the better value for a King or Twin XL, which the SweetNight does not offer.

Both are described as medium firm. The Isabella's pillow top sits on coils for a cushioned feel, while the SweetNight's Eurotop wraps gel memory foam over coils, which most sleepers find slightly more contouring.

Can I get the SweetNight in King?

No. The SweetNight listing is Queen only. The Isabella comes in Twin, Twin XL, Full, Queen and King.
