Sleepyhead’s First Edition is an 11-inch memory foam mattress with a medium feel that leans medium-firm. It cushions the shoulders and hips without the deep, slow sink of traditional memory foam. Its best qualities are motion isolation and pressure relief; the softer edge and measured response are the trade-offs. For couples and back-and-side sleepers who want a quiet foam bed, that balance works well.

The First Edition at a Glance
| Mattress | Overall Score | Pros | Cons | Ideal For |
|---|---|---|---|---|
| First Edition | 4.0/5.0 | Low motion transfer; even pressure relief; less heat buildup than typical memory foam | Average edge support; limited bounce; $99 fee on approved returns | Back-and-side sleepers; couples; hot sleepers who prefer foam |
Is the Sleepyhead First Edition Worth It?
Yes—if you want the close contouring of foam without an overly soft or sluggish surface. The First Edition held the lower back steady, eased pressure at the shoulder and hip, and kept partner movement from traveling far across the bed. It is a stronger match for back-and-side combination sleepers than for strict stomach sleepers, and it feels more secure in the middle than along the edge.
Who it’s for
- Back-and-side combination sleepers who want a medium-to-medium-firm foam feel
- Couples who value motion isolation more than bounce
- Hot sleepers who like foam contouring but do not want a stuffy surface
Who should skip it
- People who regularly sit or sleep at the edge and need a rigid perimeter
- Strict stomach sleepers who need a firmer, faster surface
- Shoppers who want several firmness choices from the same brand

How We Evaluated the First Edition
Three testers—Marcus Reed, Mia Chen, and Carlos Alvarez—used the mattress alongside my nightly sleep sessions. We kept the room, bedding, and foundation consistent, then combined sleep notes with repeatable checks for support, temperature control, pressure relief, motion isolation, response, and edge support. Position changes, edge sitting, a controlled ball drop, temperature readings, and repeat loading showed how the bed behaved beyond a quick showroom lie-down.
Sleepyhead Mattress: Our Testing Experience
First Edition
Our Testing Experience
The mattress expanded to its advertised 11-inch height within 48 hours and settled at about 6.5 out of 10 on our firmness scale. From the first week, the surface felt quiet and controlled rather than springy. A 10-pound ball dropped from 12 inches produced only a brief tremor 24 inches away, and the movement faded in about 0.8 seconds. That matches the low disturbance we noticed when one person rolled over or got out of bed.
Pressure relief varied in a useful way across body types. Mia (5'4", about 125 pounds) got enough shoulder sink for longer side-sleeping stretches without feeling trapped. Carlos (5'11", about 175 pounds) felt the most even support through his mid-back. Marcus (6'1", about 230 pounds) stayed supported on his back, although he noticed more compression at the perimeter. Under a 200-pound load, the edge compressed about 3.1 inches compared with 2.0 inches near the center, which explains why sitting at the side felt less stable than lying in the middle.
Temperature control was better than expected for dense foam. In a 72°F room, the surface warmed by 3.6°F after 30 minutes and returned close to baseline within eight minutes after the tester got up. The foam also recovered to roughly 90% of its original height in 1.6 seconds after the load was removed. That is quick enough for ordinary back-to-side turns, but the change still feels slower than it would on a coil or latex bed.
What we liked
- Very little motion reached the other side of the mattress during rollovers and exits
- Shoulder and hip cushioning stayed comfortable without letting the midsection drop too far
- The surface released heat faster than many dense memory foam beds
Who it is best for
- Back-and-side combination sleepers who want a balanced foam feel
- Couples who wake easily when a partner moves
- Hot sleepers who still prefer close foam contouring
Where it falls short
- The perimeter compresses noticeably when you sit or sleep close to it
- People who prefer a lively, springy bed will find the response too measured
- The $99 fee makes the 100-night trial less flexible than a truly free-return policy

How It Scored
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.1/5.0 | Held the hips and lower back steady during back-to-side turns |
| Cooling | 4.0/5.0 | Built up less heat than typical memory foam, though not as airy as a hybrid |
| Pressure Relief | 4.2/5.0 | Cushioned the shoulder and hip well during side sleeping |
| Motion Isolation | 4.4/5.0 | Kept partner movement from spreading across the bed |
| Responsiveness | 3.8/5.0 | Allowed normal position changes but retained some foam lag |
| Edge Support | 3.6/5.0 | Compressed noticeably when seated or loaded near the perimeter |
| Durability | 4.1/5.0 | Showed no meaningful change during break-in and repeat-use checks |
| Overall Score | 4.0/5.0 | A well-balanced foam bed with excellent motion control and a softer edge |
How the First Edition Scored
| Mattress | Overall Score | Support | Pressure Relief | Cooling | Motion Isolation | Durability | Responsiveness |
|---|---|---|---|---|---|---|---|
| First Edition | 4.0/5.0 | 4.1/5.0 | 4.2/5.0 | 4.0/5.0 | 4.4/5.0 | 4.1/5.0 | 3.8/5.0 |
Motion isolation is the standout at 4.4/5.0, and the test notes support that score: partner movement stayed local instead of traveling across the surface. Pressure relief and support both cleared 4.0, giving the mattress a balanced feel for back-and-side sleeping. Responsiveness was the lowest metric shown here, but edge support scored lower still at 3.6/5.0 in the full review. That softer perimeter is the main compromise.
Should You Choose the First Edition?
With only one Sleepyhead mattress available, the decision comes down to fit rather than model selection. Choose it if you want a medium-to-medium-firm foam surface, low motion transfer, and enough contouring to ease pressure without a deep hug. It works especially well for side sleepers who need shoulder room, average-weight back sleepers who want even support, and couples who are sensitive to movement. A cooling hybrid is a better choice if airflow and bounce matter more than motion control. Look elsewhere if you depend on a firm edge.
Where the First Edition Comes Up Short
The First Edition’s compromises are easy to define:
- The perimeter compresses enough to matter for frequent edge sitting and edge sleeping
- One feel option leaves no room to choose a softer or firmer version
- The foam recovers at a measured pace rather than snapping back
- The $99 return fee reduces the practical value of the 100-night trial
How It Compares With Other Foam Mattresses
Why choose the First Edition
- Its foam contours closely without the deepest traditional memory foam sink
- Motion isolation is strong enough for easily disturbed couples
- The washable cover makes routine care simpler
Alternatives to consider
Casper Snow is the better choice if you want a cooling-focused hybrid and are willing to pay more for it. Its coil core, zoned support, phase-change material, cool-touch cover, and HeatDelete bands create a more elaborate cooling system, while the Sleepyhead stays quieter and simpler.
Nectar Premier Memory Foam is the stronger option if you want more time to decide. It is a 13-inch foam mattress with a 365-night trial and a lifetime warranty, compared with Sleepyhead’s 100-night trial and 10-year foam warranty. Sleepyhead has the advantage if you prefer a lower 11-inch profile and a washable cover.
T&N Original suits sleepers who want a quicker, more buoyant foam response. Its current Flex, Release, and Adaptive foams are designed to recover faster than memory foam. Sleepyhead is the more convincing pick when motion isolation and closer contouring matter more than bounce.
Getting the Best From the First Edition
- Use the full 30-night adjustment period before deciding whether the firmness works for you.
- Pair the mattress with a thin, breathable protector; a thick padded cover can hold heat near the surface.
- Use a sturdy, ventilated base with slats no more than three inches apart. Queen and King frames also need center support.
- Choose a pillow that matches your shoulder width and sleep position instead of trying to correct alignment with a very tall pillow.
- If you share the bed, judge motion isolation during your normal nighttime routine, not from a single showroom test.
- Rotate the mattress periodically, especially if one partner is heavier or you sleep on the same side every night.
- Mark the end of the 100-night window and remember that an approved mattress return carries a $99 fee.
FAQs
Is the Sleepyhead First Edition good for side sleepers?
Yes, particularly for light- and average-weight side sleepers. The foam gave the shoulder and hip room to settle without allowing the midsection to drop too far. Heavier side sleepers who prefer deep contouring may want a softer comfort layer.
Does it have the “stuck” feeling of traditional memory foam?
Not to the same degree, but it is not springy. The foam recovered to about 90% of its height in 1.6 seconds after unloading, so ordinary turns felt manageable while quick changes still had a little lag.
Is it a good mattress for couples?
Yes. Motion stayed close to its source during partner-movement checks, making the First Edition a good option when one person changes position often or gets up earlier.
Is the edge firm enough for everyday sitting?
It is usable but not firm. The perimeter compressed more than the center under the same load, so people who sit there while dressing or sleep at the very edge will notice less stability.
