The build
Harbor puts Meltcore over Coilwell pocket coils. You get the lift of a spring bed and much of the quiet of a foam one. Medium-firm, for people who do not sleep in only one position.
Harbor is the bed we expect most people to start with. It is 28 cm tall, supportive through the middle, and still willing to meet a shoulder. Couples tend to land here because the coils keep one person’s turn from becoming the other person’s problem, and the foam keeps the surface from feeling wiry.
A good fit if
- Combination sleepers
- Couples
- Back sleepers who want an easy default
- Anyone replacing a worn spring bed
In this build
- Meltcore
- Comfort foam that softens with warmth where you lie, and stays more supportive a short distance away.
- Coilwell
- Pocketed steel coils, each in its own fabric well, so one person’s turn stays local.
- Airveil
- An open knit cover. Air can move. The cover unzips and washes cool.
- Quietseam
- Edge-to-edge quilting that keeps the surface calmer when someone else moves.

Shipping and the trial
Thaw mattresses are compressed and boxed. You unroll them. We do not send a crew, and we do not take the old bed away.
The trial is the point of selling a mattress in a box. Sleep on it. If it is not yours, we take it back.

Questions on this one
How firm is medium-firm?
On our feel guide it sits at 7 of 10. You should not sink to the coils. Side sleepers who want more give often prefer Drift or Loom in Plush.
Can I use it on a slatted base?
Yes, if the slats are no more than about 7 cm apart, or on a solid platform. A sagging base will void the sag cover in the warranty.
Is there a set?
The Harbor Set is this mattress plus a Keeper protector and a Rest pillow, priced as one line. You can also buy the pieces apart.
