Which is better for back pain?

The Saatva Classic. Its Lumbar Zone coil design and three firmness levels let you tune support, and Saatva reports 93.9% of surveyed buyers said it eased back pain. The Polysleep's single medium-firm foam build suits many sleepers but offers no adjustment.

The Saatva Classic is the safer bet for longevity. Its dual-coil design with over 1,000 recycled steel coils is built to resist sagging, while all-foam mattresses like the Polysleep tend to soften sooner, especially for heavier sleepers.

Is the Saatva worth the extra money?

At $1,599 versus $669, you pay about $930 more for a firmness choice, cooler coil sleep, a 365-night trial and GREENGUARD Gold certification. If you sleep hot, share a bed, or need firmer support, it can be worth it. If budget rules, the Polysleep covers the basics.

Which is better for couples?

It depends on what bothers you. The Polysleep's foam absorbs motion, so a restless partner disturbs you less. The Saatva sleeps cooler and comes in three firmness levels, so partners with different preferences have more room to compromise.

Which is better for hot sleepers?

The Saatva Classic. Its coil core and breathable organic cotton cover move air better than an all-foam build. The Polysleep's open-cell foam helps, but foam still traps more heat.

Does the Polysleep work in a Murphy bed?

Yes. It is 10 inches thick, folds, and needs no box spring or strapping, which is why it is sold for Murphy beds. The Saatva Classic is a thick innerspring and is not designed to fold.
