Sealy Posturepedic Spring Bloom 12" Medium Mattress
Was from: $499.99
Now from: $299.99
Saving: Up to $400 at Mattress Firm 

Summary: Sealy’s entry-level orthopedic mattress, the Posturepedic Spring Bloom is an innerspring style mattress made up of an antibacterial cover, Sealy cool gel foam and motion-reduce encased coils for comfort and correct spinal alignment. There’s also a reinforced foam center that provides targeted back support. Orthopedic mattresses are some of the best mattresses for back pain, although the Sealy Posturepedic Spring Bloom is softer than many others on the market. It’s available in a medium firmness that should appeal to back sleepers and possibly even some stomach sleepers, as it has such a firm and reinforced coil. Like the best mattresses for side sleepers, the medium soft mattress offers plenty of cushioning comfort around the pressure points of the shoulders and hips, whilst still maintaining excellent spinal alignment. Motion transfer is also excellent, so this is a good choice if you share your bed with a restless partner.

Price history: Even at full price, the Sealy is competitive, with a queen coming in at $699. The 40% flash sale takes this down to an epic $419.99, which is rivals the best prices on many of the best mattresses on Amazon. This is one of the strongest discounts we’ve seen on the Sealy Posturepedic range, so it’s well worth taking advantage if you’re looking for a new orthopedic mattress.  

Benefits: 120-night trial | 10-year warranty | Free white glove delivery

What is an orthopedic mattress? 

An orthopedic mattress is one that’s designed to promote healthy spinal alignment alongside great support and pressure relief. They generally provide firmer support, due to reinforced coils and extra lumbar support and are particularly suited to those suffering with joint and back pain. 

Orthopedic mattresses are generally made using higher quality materials and a sturdy design, meaning that they offer plenty of longevity. Most true orthopedic mattresses are innerspring or hybrids, with the foams providing cushioning, while the springs provide the support. These mattresses are ideal for back pain sufferers who need to make sure their lumbar region is adequately supported to avoid the spine falling out of alignment.
