Baby Mattresses

Posted on Leave a comment

Since we have cut quite a few pieces of latex over the years for infant bassinets, playpens, crib mattresses, etc., I thought I would share a few tips we have learned along the way. If you have feedback on your particular brand’s frame and how our products work with it, let me know and I’ll add it to this post.

Keep in mind that we cut and sew to your dimensions. We can cut latex, sew puddle pads, sheets, tickings, receiving blankets, you name it. Contact us for a quote or see the latex calculator here.

TIP 1: Cut the latex 1″ larger and sew the ticking 1/2″-1″ larger.

Latex is very flexible. That translates to when we cut it to the exact inside dimensions of your crib, you may find that the ticking or even sheet will pull it a little bit smaller than we cut it. While the mattress will still be completely usable, of course, not having that extra 1/2″ of nothing between the side wall.

The softer the latex is, the more flexible it is. So even a 3″ soft will be constrained by the sheets and ticking.

Tip 2: Latex can be cut down to .5″ in a Hard D90 firmness only.

Again, latex is very flexible and the softer layers are too floppy to cut thinner. To note, the thinner the latex is, the softer it feels, so if you are wanting a firm, thin surface for your infant, a hard is a great way to achieve that feel.

Tip 3: Most parents want firm mattresses for their infants.

If your child is able to roll over, I encourage you to consider all the firmnesses we offer, from Soft to Hard as options. A 3″ soft adds significant comfort to those hard pack n’ play mattresses, but is not firm. Keep in mind that little bodies sink through only a little and a soft feels super squishy to us and only a little squishy to them.


  • Snoo Mattress: Cut hard latex to .75″.
  • Guava Lotus travel crib: The crib sides are much more flexible than a regular pack n play, so add an extra .5-1 inch on all sides of the latex pad for it to not have gaps between the mattress and the mesh walls.
