Questions and answers
- Which is better for side sleepers?
- The Bear Original. Its medium-firm foam relieves pressure at the shoulders and hips, while the Sealy Seafield is a firm innerspring that many side sleepers find too hard.
- Which lasts longer?
- The Bear Original is the safer bet. It carries a 10-year warranty, while Sealy Seafield buyers report sagging after one month and no warranty term is stated.
- Is the Sealy worth the extra?
- It is not extra right now. The Sealy last listed at $582.30 as of November 1, 2026, below the Bear's $648.70 at Bear Mattress as of November 3, 2026, but it includes a box spring and has sagging complaints.
- Which sleeps cooler?
- The Bear Original. Its gel swirl foam and Celliant cover target heat, and reviewers scored it 4/5 on cooling. The Sealy is a foam-topped innerspring with no cooling claims.
- Which is better for couples?
- The Bear Original, because its motion isolation keeps movement from carrying across the bed. The Sealy's coils transfer more motion.
- Do I need a box spring for either?
- The Sealy Seafield set includes one. The Bear Original is mattress only, so you need a foundation or platform bed.
