Baby’s Little Place Reviews

The Oxford Baby Harper 4-in-1 convertible crib is a relatively popular baby crib. It is one of the best-selling convertible cribs of big retailers, such as Walmart, so you can find many online reviews by people who already have it.

Most parents are pleased with the crib, but there are also negative reviews. So, what to believe? Although parents’ opinions can be helpful, they can also be misleading. Why?

For example, if there is a negative review due to a missing toddler bed guardrail, it is irrelevant! Why? Because the parent who negatively reviewed Oxford Baby Harper 4-in-1 convertible crib didn’t read the description well.

The Oxford Baby clearly stated that this is a convertible crib, but you have to buy a safety rail to convert it into a toddler bed. So, in this case, the Oxford Baby Harper crib shouldn’t be rated negatively.

Now let’s look at its lower ratings due to the crib’s softwood construction which is liable to damage by dings and scratch. Some parents mentioned this issue; however, most didn’t rate the crib very low. In the “design and specification section” of this Oxford Baby Harper 4-in-1 convertible crib review, find the reason why.

Baby’s Little Place tip: Parent reviews will give you helpful information, but do not consider only the reviews’ stars. Read why they’ve rated it so, and thoroughly think about it.

Design and Specifications

The Oxford Baby Harper is a traditional but modern-looking crib. I like its classic open slat silhouette that makes the crib airy and enables seeing your baby from any angle of the room. Streight modern lines with a bit of curved contrast on the headboard are certainly a winning combination.

Weighing just 33 pounds, the Harper ranks among lightweight but sturdy cribs! I like its square feet, which add to its stable construction and prevent wobbling.

Another great thing about this crib is its raised, carefully designed headboard. It has an open silhouette with a closed top, so you can place it next to the wall or in the middle of the room. I think it looks great in both cases.

A raised headboard has another benefit. It provides a better-looking Harper when converted into a full-size bed.

Overall it is a nice-looking crib. Yes, there are some visible holes where the bolts go together, but this is a minor cosmetic issue, and I guess you can find caps to hide them if they bother you.

Is Oxford Baby Harper 4-in-1 convertible crib suitable for short moms?

Another thing I want to point out is the Oxford Baby Harper’s height. The stated height (39.5″) of the crib is the height of the Harper’s headboard. The front panel and sides are about 32 inches in height, making the crib suitable for short moms.

Why is a softwood not a dealbreaker?

The Oxford Baby Harper 4-in-1 convertible crib is made of Pine Wood. That is an inexpensive but sturdy wood, a rare but perfect combination for affordable baby cribs.

Softwood does not compromise the safety and sturdiness of a crib! However, it is more easily dinged, nicked, or scratched, and the Oxford Baby Harper crib is not an exception.

However, you can prevent most damages with proper care and caution in assembly. But to avoid it altogether, you will have to decide on a super high-end crib (at least $500 and up) made of hardwoods.

So, since this is common to all low and middle-priced cribs, I wouldn’t say it is a dealbreaker!

Oxford Baby Harper convertibility Review

The Oxford Baby Harper 4-in-1 convertible crib adapts and grows with your child from infancy to toddlerhood and into teen years.

It can convert into three beds; Toddler Bed, Daybed, and Full-Size adult bed, but you will get only parts for the conversion into a Daybed with the crib.

Conversion kits for the other two beds are sold separately, meaning you will have to buy a Harper Guard Rail for a toddler bed and a Harper Full Bed Conversion Kit for an adult bed.

Since this is common practice with all crib brands, I do not consider it negatively. Harper’s guard rail is also cheaper than most other guard rails on the market. You will get it for only $49.99, making the overall price just about $200.

Although tracking down the Oxford Baby conversion kits is not hard, and they are in stock most of the time, I recommend you buy a toddler bed safety rail now, just in case it becomes unavailable later.

Harper Collection

This crib is a part of an Oxford Baby Harper collection. You can buy a matching changing table, drawer dresser, or even opt for a Harper combo crib.

The combo crib is a crib with an attached changing table. Such a crib is a perfect choice for those who can’t fit a stand-alone crib and changing table in the room.

A combo crib costs more, but you get a convertible crib, changing station, and storage units combined in one piece of space-saving furniture.

The Harper combo crib’s conversions are the same as those on the regular Oxford Baby Harper 4-in-1 convertible crib. Its changer stays attached to a toddler bed and daybed and detaches in the last conversion into a full-size bed.

The Harper combo crib has a quality-made changing station, with one shelf, one spacious storage drawer, and a changing area on top. A fitting changing pad is included in the purchase.

Safety Review

The Harper crib undergoes rigorous testing to exceed all Federal Safety Standard! Its meets all applicable safety standards set by the ASTM (American Society for Testing and Materials) and CPSC (Consumer Product Safety Commission).

Crib’s finishes are lead-free, formaldehyde-free, and non-toxic.

Their Customer Service, which is very responsive and helpful, reassured me safety is their #1 priority, and I believe them. They even employ a 3rd party laboratory to test finishes to ensure that they are the safest on the market.

The Oxford Baby Harper crib is also GreenGuard® GOLD-certified, meaning it doesn’t pollute the indoor air!

Oxford Baby Harper’s safety specifications:

  • MEETS: all applicable ASTM and CPSC standards
  • CONSTRUCTION: sturdy and strong, doesn’t wobble
  • DROPPING SIDES: no (such sides are banned since 2011!)

Oxford Baby Harper 4-in-1 Convertible Crib Review | Convertibility


The Oxford Baby Harper 4-in-1 convertible crib has everything your child needs from infancy to teens and beyond. Well, if you buy the conversion kits for the transitions. Nevertheless, you will get a crib with adjustable mattress support that converts into a daybed without additional costs. For less than $150, I really think it is worth it.

    1. Just looking at styles and dimensions to build one for granddaughter. Noticed your dimensions seem way off – if front rail is 32” from floor and upper platform adjusts to 26.5” from floor, adding a 5” mattress leaves only .5” to rail! Even if that is floor to top of mattress, it’s only 5.5” which does not sound right. Think you may need to double check how you measure and report.

      1. You have right! I do not understand where those measurements came from, and I am sorry on behalf of the whole Baby’s Little Place team. The front rail is indeed 32″ in height, but the mattress position heights were wrong.

        The mattress height levels are approximately 7″, 11″, and 15″, measured from the floor to the top of the spring frame. So, by using a 6″ mattress, which is the maximum allowed thickness, there is still 11″ from the mattress’s top to the top of the rail.
