What Is the SleepKing Casey TT?
The Casey TT (Tight Top) is a hybrid mattress from SleepKing, a Canadian manufacturer. The "two lives" description refers to its flippable design: comfort layers on both the top and bottom surfaces allow you to flip the mattress periodically, alternating which side you sleep on.
Flippable mattresses were the industry standard until the early 2000s, when most manufacturers switched to one-sided designs. The Casey TT is one of the increasingly rare models that maintains the two-sided approach. For a deeper comparison, see our flippable versus one-sided mattress guide.
Construction and Materials
The Casey TT uses a hybrid construction:
- Support core: Individually wrapped pocketed coils, which provide targeted support and reduce motion transfer between sleep partners.
- Comfort layers (both sides): Foam comfort layers on both the top and bottom, creating two usable sleep surfaces with similar comfort characteristics.
- Tight top design: The comfort layers are sewn flush with the mattress surface (no pillow top or euro top). This gives a firmer, more supportive feel compared to plush pillow-top designs.
The pocketed coil system provides better airflow than an all-foam mattress, which helps with temperature regulation. Each coil moves independently, so when one partner shifts position, the movement is absorbed locally rather than traveling across the entire mattress surface.
Tight top vs pillow top: A tight top mattress has a firmer, flatter surface. A pillow top has an additional cushion layer sewn on top, creating a softer, more plush feel. The Casey TT's tight top construction is better suited to back sleepers and those who prefer firm support. If you prefer a plush feel, this may not be the right model. Our firmness guide can help you determine which feel suits your sleep position.
The Flippable Advantage
The practical benefit of a flippable mattress is longevity. Foam and fibre comfort layers compress under repeated body weight. Over time, this creates body impressions where your hips and shoulders rest. By flipping the mattress every three to six months, you allow the compressed side to recover while using the fresh side.
Research on polyurethane foam resilience shows that periodic unloading extends usable foam life by 30 to 50 percent compared to continuous one-directional loading. In practical terms, a flippable mattress that would otherwise last 7 to 8 years can last 10 to 12 years with regular flipping.
The trade-off: each side has thinner comfort layers than a comparable one-sided mattress (which puts all its comfort material on one side). The Casey TT may feel firmer initially than a thick pillow-top. This is a feature for people who prefer firm support, but something to be aware of if you prefer plush.
Flipping schedule: Flip the Casey TT every three months (when the seasons change is an easy reminder). Rotate it 180 degrees at the halfway point between flips. This four-step annual rotation distributes wear across the entire mattress surface evenly.
Who This Mattress Suits
- Value-focused shoppers who want a mattress that lasts longer than average. The extended lifespan from flipping reduces the cost per year of ownership.
- Back sleepers who prefer firm, supportive surfaces. The tight top construction keeps the spine aligned without excessive sinking.
- Couples who benefit from pocketed coil motion isolation and who are willing to flip the mattress together every few months.
- Hot sleepers who want the airflow advantage of a coil system combined with moderate foam comfort.
This mattress is less suited to dedicated side sleepers who need thick comfort layers for hip and shoulder pressure relief, or to people who want a plush, sinking-in feel.
How It Compares
| Feature | Casey TT (Flippable) | Typical One-Sided Hybrid |
|---|---|---|
| Usable surfaces | 2 | 1 |
| Expected lifespan | 10-12 years | 7-8 years |
| Initial comfort feel | Firmer (thinner layers per side) | Softer (thicker comfort on one side) |
| Maintenance | Flip every 3 months + rotate | Rotate only |
| Motion isolation | Good (pocketed coils) | Good (pocketed coils) |
| Temperature | Good (coil airflow) | Good (coil airflow) |

Call 519-770-0001Brad, Owner, 40+ years of experience: "Flippable mattresses fell out of fashion because they cost more to manufacture. Most companies switched to one-sided designs in the early 2000s and called it an improvement. It wasn't. The reason we carried two-sided mattresses through that period and still carry them now is simple: twice the sleeping surface means twice the lifespan if you actually flip it. The Casey is the one we recommend when customers want real longevity without paying luxury prices."
Frequently Asked Questions
Is the SleepKing Casey TT a good mattress?
It is a well-built flippable hybrid that suits value-focused shoppers and back sleepers who prefer firm support. The flippable design extends lifespan significantly. It may be too firm for side sleepers who need plush pressure relief. Testing in person is the best way to assess fit.
How often should I flip the Casey TT?
Every three months. A simple routine is to flip when the seasons change and rotate 180 degrees at the midpoint between flips.
Does the Casey TT need a box spring?
It works on a box spring, platform frame, or slatted frame with slats spaced no more than 3 inches apart. A box spring is not required but is compatible if you prefer the additional height.
How long does the Casey TT last?
With regular flipping and rotation, 10 to 12 years. Without flipping, closer to 7 to 8 years, similar to a one-sided mattress.
