9 Best Cribs with Adjustable Mattress Height (November 2026)
The best cribs with adjustable mattress height include the Dream On Me Synergy 5-in-1 Baby Crib for steel support, the Dream On Me Violet 7-in-1 Convertible Life for conversion choices, and the Graco Benton 5-in-1 Convertible Crib for 4-position flexibility.
On this page (6 sections)
The best crib with adjustable mattress height for most families is the Dream On Me Violet 7-in-1 Convertible Life, with 4 height settings and several conversion options. If you prefer a steel mattress support frame, consider the Dream On Me Synergy; the Graco Benton and DaVinci Charlie also provide 4 mattress positions.
A crib's adjustable mattress support lets you change how high the mattress sits inside the frame. That feature can make it easier to reach a newborn, then give you lower positions as your baby grows.
The picks below have 3 or 4 mattress support positions. They differ in conversion stages, materials and which rails or kits come separately.

Which cribs with adjustable mattress height stand out?

How do the mattress positions compare?
The Benton, Charlie, Teddi, Violet and Birdie have 4 listed mattress positions, while the Synergy, both Essex models and Aurora have 3. The number of positions is useful for comparing flexibility, but it doesn't replace checking the manual for adjustment steps.

A crib with more positions gives you more preset support heights to choose from. The actual fit depends on the mattress and frame, so use only the mattress size and setup allowed by the crib instructions.
The number of later bed stages is a separate decision. A crib may offer several conversions, but rails and kits can be separate purchases.
What does adjustable mattress height mean?
Adjustable mattress height means the mattress support platform can be set at different heights within the crib. It does not mean the crib's side rail moves.
Many models here offer 3 or 4 positions. Use the crib manual to learn how to secure the platform at each setting, and lower it as directed as your baby develops.
For a clear distinction between platform settings and side rails, read Convertible Crib With Adjustable Side Rail: What to Know. If you're considering a movable rail, our guide to Crib With Adjustable Railing: What to Know covers that separate feature.
How should you choose between 3 and 4 positions?
Choose 4 positions if you want more preset heights to compare as your baby grows; choose 3 if the model's other features fit your needs. The Violet, Benton, Charlie, Teddi and Birdie have 4 settings, while the other picks have 3.
Position count alone doesn't determine whether a crib suits your room or plans. Compare dimensions, conversion parts, mattress requirements and the configuration you expect to use.
A rocking feature is different from mattress height adjustment. If you are also considering movement, our guide to a baby crib rocker explains what to look for.
What else should you check before choosing?
Check the crib's mattress requirements, included rails, conversion parts and dimensions before settling on a model. The details vary even among cribs with the same number of height positions.
A standard full-size crib mattress is sold separately for several of these options. For mattress stage details, see What Exactly Is a 2 Stage Crib Mattress for New Parents?.
Also check which parts come with the crib. The Delta Essex includes its daybed or sofa rail, while the Violet, Synergy, Benton, Charlie, Teddi, Birdie and Aurora identify conversion parts that are sold separately.
Our score weighs the listed specifications and features against what shoppers looking for adjustable mattress height need. We compared the number of support positions, conversion options and relevant included parts.
Which adjustable-height crib should you pick?
Pick the Violet if you want 4 mattress positions and a wide range of conversions, or the Synergy if its steel support frame is your priority. Choose the Benton or Charlie for 4 positions with different materials and design details, and compare included rails and separate kits before buying.

Frequently asked questions
How many mattress height positions should a crib have?
A crib with 3 or 4 mattress positions gives you options as your baby grows. A higher position can make reaching a newborn easier, while a lower setting is used as a baby begins to sit, pull up or stand.
Follow the crib manual for when and how to adjust the support.
Are adjustable mattress height and adjustable railing the same?
No. Adjustable mattress height refers to moving the mattress support platform to different positions inside the crib.
An adjustable railing refers to a movable side rail, which is a different feature.
For details about the rail feature, see our guide to cribs with adjustable railing.
Do convertible cribs include the parts for later bed stages?
Not always. Some cribs include a daybed or sofa rail, while toddler guardrails, full-size rails and other conversion parts may be sold separately.
Check which parts are included for the specific model and stage you plan to use.
Does mattress height adjustment change the crib's side rail?
No. The mattress support moves to a different height inside the crib; the side rail itself does not move as part of that adjustment.
Lower the support as your baby develops, following the crib's instructions.
Don't confuse mattress platform positions with an adjustable side rail.
