- Is the Serta Classic Blissville good for side sleepers?
- A medium feel works for some side sleepers, but lighter side sleepers may want more cushioning at the shoulder and hip. Heavier side sleepers often find a medium coil mattress too firm.
- Does it need a box spring?
- It works on a box spring, a slatted bed base or an adjustable base. A firm, flat foundation protects the warranty and keeps the coils supported.
- How firm is medium?
- Medium is roughly a 5 to 6 on a 10-point firmness scale. It is softer than a firm mattress and firmer than a plush one, so most back and stomach sleepers find it supportive.
- Is $479.99 a good price for it?
- That is the only new price listed, at Mattress Firm as of November 8, 2026, so there is little to compare against. Entry-level Serta coil mattresses commonly sell in the $400 to $700 range.
- How long should it last?
- A budget coil mattress typically lasts six to eight years with regular rotation. Heavier sleepers should expect the shorter end of that range.
- Does it come in a box?
- It is a traditional innerspring mattress, not a bed-in-a-box, so expect delivery rather than a compressed roll. Check the included foundation and delivery terms with the store.
- Where is the Serta Classic Blissville 11.5 Medium Mattress cheapest?
- At Mattress Firm, for $479.99, as of our latest check.
