Flwrgirl Baby Bassinet Bedside Sleeper: Best for bedside height adjustment
- Six adjustable heights
- Mattress included
- Four wheels
- 36 x 22-inch size
This bedside sleeper has six adjustable heights and a mattress, with a stated size of 36 x 22 inches. Check the fit with your bed and follow its instructions for setup.

- Six adjustable heights

Choose it if bedside access and six height settings are the main needs. Follow the setup and use instructions for the sleeper and confirm it fits your intended placement.
How we compared adjustable mattress heights
We compared the stated number of mattress positions, any published height measurements, included mattress or pad, folding features, and conversion options. Our score weighs specs and features against what you're shopping for: a compact crib whose mattress can be lowered as your baby grows.
A higher position can make it easier to reach a newborn, while a lower position is intended for later development stages. The crib manual should guide when to move the support, since the right timing depends on the crib and your baby's development.
The number of positions alone doesn't show how far apart the settings are. When exact measurements are available, compare them with your needs; when they're not, use the manual and product dimensions to understand the setup.

What should you compare before choosing a height setting?
Compare the height measurements, adjustment steps, and mattress compatibility before choosing a mini crib. The crib must use a mattress that fits the model, and the mattress support needs to be set according to the manufacturer's instructions.
A model with 4 settings doesn't always give more useful spacing than one with 3. Published heights, as on the Aden and Jayden, show where the mattress support sits relative to the floor and make comparisons more concrete.
Also confirm whether the crib comes with a full mattress or a thin pad. The adjustable mattress height crib guide explains how the support positions work and why the manual matters.
When should you lower a mini crib mattress?
Lower the mattress when your baby's development reaches the stage named in the crib instructions. Several cribs here describe a lower position as appropriate when a baby starts sitting, pulling up, or standing, but follow the specific manual for your model.
The Delta says to lower its mattress as a baby begins to sit or stand. Dream On Me gives three measured steps for the Aden and Jayden, while the other models provide different position counts or less detail about exact heights.
Check the mattress support locks after every adjustment, and make sure the mattress remains compatible with the crib at each setting. If you’re unsure about the steps, contact the crib maker before use.
Is a convertible mini crib the same as an adjustable-height crib?
No. Adjustable height changes the mattress support position inside the crib, while convertible describes a crib that changes form as your child grows.
A crib can have one feature, both, or neither.
The Aden, Graco Stella, DaVinci Dylan, Synergy, Jayden, and Violet combine adjustable height with conversion options. Review each model's conversion details and required kits in our guide to the best convertible mini crib.
If you only need to change the mattress position, conversion may not affect your choice. If you want the crib to become a daybed or twin bed, check which parts are sold separately.
Which adjustable height mini crib should you choose?
Choose the Dream On Me Aden if you want three measured mattress heights and a crib that can convert to a mini daybed and twin bed. Choose the Graco Stella or DaVinci Dylan if you prefer four height options, and the Delta if folding flat is the leading need.
For a mattress included, compare the Graco Stella and Synergy, then review the dimensions and conversion kit requirements. If bedside height adjustment is the priority, consider the Flwrgirl sleeper as a distinct bedside option rather than a conventional convertible crib.
Read the manual for the position change schedule, and make sure the mattress fits the crib before use.

Follow the crib manual for when to lower the mattress as your baby develops.
When should you lower a mini crib mattress?
Lower the mattress according to the crib maker's instructions, especially as your baby begins to sit, pull up, or stand. Some cribs have a specific lower position for these stages.
Check the manual for the exact timing and position, since models differ.
