Is the BedStory Green Hybrid good for side sleepers?

It is medium-firm, which many side sleepers find too hard on the shoulder and hip. Side sleepers who like a firm bed may be fine; those who want cushioning should look at a softer mattress.

What is the sleep trial and warranty?

BedStory offers a 365-night sleep trial and a 10-year warranty. That trial is much longer than the 100 nights most mattress brands give.

Does it need a box spring?

It is a hybrid with its own coil support, so it works on a platform bed, slatted frame or adjustable base. A box spring is not required.

How does it compare with an all-foam mattress?

The coils give more bounce and airflow than all-foam, but the bed is heavier and isolates motion less well. All-foam beds are easier to move and quieter for couples.
