Is this mattress soft or firm?

The listing gives conflicting signals: the firmness field says firm while the fill style says soft. Treat it as a soft hybrid and confirm the feel with the seller before ordering.

What size is 38 by 79 inches?

That is a twin XL, the length of a twin with extra legroom. It fits twin XL frames, adjustable bases and most dorm beds.

Do I need a box spring?

No box spring is required, but no foundation is included. Use a slatted base, platform bed or adjustable base; a rigid slatted frame is the safest choice for a hybrid.

Is it good for side sleepers?

Yes. The soft gel foam layer cushions the shoulder and hip, which side sleepers usually want, while the coils keep the spine supported.

It is marketed as cooling, with ventilated construction and gel foam. Most hybrids sleep cooler than all-foam beds, but no mattress is actively refrigerated.

No price was given for this listing, so no low point can be identified. Mattress prices typically drop around major holiday sales and during model-year clearance.

Our take on the Sealy Posturepedic Plus Hybrid Soft Tight Top Mattress

The Sealy Posturepedic Plus Hybrid Soft Tight Top is a hybrid mattress that pairs gel memory foam with fabric-encased coils and a reinforced DURAFLEX edge. It is listed here in a 38-inch by 79-inch size, which is a twin XL, and the spec sheet calls the firmness soft while also listing a firm level, so confirm the feel before buying. It is CertiPUR-US certified and sold without a foundation, though it works on an adjustable base. No price was provided for this listing, so its current cost against its recent range cannot be stated.
