Quick response
Ordered a gate prior to this one, UPS lost it on route. I reached out to Kidsy via email and they secured a refund from UPS. Was hesitant to order again, but I couldn't find the gate at a more reasonable price. 2nd order arrived with no issues. Gate is sturdy and the dog (Husky) hasn't gotten through it (he's an escape artist). Quick delivery from start to finish.

Kidsy Customer Service Review
Kidsy had a great selection of deeply discounted baby gates. Unfortunately, there was a piece missing when I received my package. I didn't realize it until after the 14 day return/exchange window. But I reached out, and they were willing to send me the piece anyway at no extra charge. I really appreciated the customer service.
I appreciated the detailed description
I appreciated the detailed description, I knew I was getting a floor model and it came in perfect shape at a much reduced cost. When I thought the cupholders weren't included, I reached out to them and then we found them and they were very responsive and thankful that I let them know. Everything is fine.
Great, trustworthy experience
Great deals, easy checkout with lots of payment options, shipped very quickly, and everything was packed well and looked exactly as it was described! I didn't end up needing any intervention with my shipping experience but appreciate the option to cover lost packages for a minimal fee, especially as we get into the late and lost package holiday season. I'll definitely be getting more of my baby gear from Kidsy.
Good experience
Item arrived just as described. Couldn’t be happier.
So easy to use
Website is easy to use, items are great quality, and shipping is fast.

Q&A
10 answered6 Questions Answered
4 high confidence · 3 web-sourced
What is the mattress's exact thickness (in inches and mm) and what manufacturing tolerance should I expect (e.g., ±0.1")?
This mattress is listed with a height of “< 6 in” (under 6.0 in, i.e. under ~152.4 mm) on the product page; an exact finished thickness for this SKU is not published. We don’t publish a model-specific manufacturing tolerance either, but industry/procurement specs for crib mattresses commonly allow about ±1/4 in (±6 mm) as a practical expectation. [1][2][3]
Sources
Delta Children product page (product dimensions); Naturepedic / Pottery Barn Kids product page (example manufacturer tolerance ±1/4") ; Ohio procurement mattress spec (tolerance guidance).
Is the waterproof cover removable (zippered or otherwise) and is it machine washable or only wipeable? If machine washable, what temperature and care instructions apply?
This Serta Perfect Start mattress has a durable waterproof vinyl cover (both sides) that the Delta Children product page lists as a wipe‑clean vinyl surface and does not describe as a removable/zippered cover. [1][2] We recommend spot‑cleaning with a damp cloth and mild soap and letting it air dry — do not machine wash, bleach, or expose the vinyl to high heat (machine washing/drying can damage vinyl covers). [3]

Delta Children product page; independent product review/retailer listing indicating cover is not removable; vinyl mattress-cover care guidance
Has this mattress been tested for breathability or heat retention (e.g., airflow rate, surface temperature rise), and should parents expect any noticeable vinyl/heat trapping compared with typical foam or innerspring crib mattresses?
We don’t publish any formal airflow-rate or surface‑temperature test numbers for the Serta Perfect Start; the product listing shows a firm polyester fiber core with a dual‑sided waterproof vinyl cover but no breathability test data. [1] Waterproof vinyl covers over a fiber or foam core are generally less breathable than innerspring or mattresses designed specifically for airflow and can feel a bit warmer at the surface, so parents in hot/humid environments may notice slightly more surface warmth than with a ventilated/breathable model. [2][3]
Sources
Delta Children product page; Consumer Reports guidance on mattress materials; independent crib‑mattress breathability guide
Can you quantify the firmness (for example an ILD rating or a statement of meeting AAP firm‑sleep guidance) and confirm this mattress is appropriate for newborns and recommended sleep positions?
We do not publish an ILD (Indentation Load Deflection) number for this model; the Serta Perfect Start is built with a firm polyester fiber core and is sold/marketed as an infant‑grade, firm crib/toddler mattress (dual‑sided waterproof cover, GREENGUARD Gold, fits standard cribs). The American Academy of Pediatrics recommends that infants sleep on their backs on a firm, flat mattress with only a fitted sheet — this mattress is designed to provide the firm surface the AAP recommends for newborn sleep. [1] [2]
Sources
product_description; AAP safe‑sleep guidance (HealthyChildren.org)
Is the cover dual‑sided in the sense that both sides are usable (i.e., flip to extend life) or does "dual‑sided" refer only to waterproofing on both faces? If both sides are usable, is there any difference in feel between sides?
Both sides are usable — “dual‑sided” refers to a waterproof vinyl cover on both faces so you can flip the mattress to extend freshness and life. There’s no different surface or feel specified; both faces cover the same firm polyester fiber core and should feel the same under baby.
product_description; features & specs (dual‑sided waterproof cover, firm polyester fiber core)
Are standard fitted crib sheets and mattress protectors (designed for up to 6" depth) guaranteed to fit snugly on this mattress, and what is the finished corner radius/square corner dimension so I can check for potential gaps in my specific crib model?
Yes — standard fitted crib sheets and waterproof protectors rated for up to 6" depth are compatible with this mattress: it is sold as 27.5" W × 52" L × under 6" H and finished with square corners to help create a snug fit. [1] The manufacturer does not publish a numeric finished corner‑radius measurement; the spec simply notes “square corners,” so to check for gaps measure the mattress in your crib after unboxing (no more than two fingers of space is recommended for a safe fit). [1][2]

Merchant FAQs
- What is the Standard Size of a Crib Mattress?
- The Consumer Products Safety Commission (CPSC) requires all full-size baby crib mattresses to be at least 27 and 1/4 inches in width by 51 and 1/4 inches in length, with a maximum thickness of six inches. For cribs, the standard size varies; check the crib’s box and/or assembly instructions for recommended mattress size.
- What is the Standard Size of a Baby Crib?
- The CPSC requires that full-size baby cribs have a standard width of 28 inches and a standard height of 52 and 3/8 inches, with a “pull or minus factor” of 5/8 inches. Because of this variation, consult the crib’s recommended mattress size.
- How Can I Tell if a Crib Mattress Fits in my Crib?
- Crib mattresses should fit very snug or moderately snug in the crib. No more than two fingers of space should exist between the side of the mattress and the crib frame. A mattress that is too small could be a suffocation and entrapment hazard.
- How Firm Should a Crib Mattress Be?
- The firmer, the better for crib mattresses. Soft surfaces can pose a suffocation hazard and increase SIDS risk. Test firmness by pressing the center and edges — the mattress should snap back immediately.
