The best dog bed cushion insert is one that matches your bed cover’s interior dimensions and provides the support your dog needs. The EechicSpace foam inserts are best for replacing a flattened cushion while keeping an existing cover; the 30 x 20-inch size suits smaller beds, while the 36 x 24-inch and 36 x 27-inch options fit larger spaces. The KSIIA bed is a complete bed rather than a bare insert, and the EechicSpace liner adds a waterproof layer around compatible foam.

EechicSpace 30 x 20-Inch Egg Crate Foam Insert
This 30 x 20 x 3-inch insert is a replacement cushion made from 30D egg crate foam. The listed features describe firm, responsive support designed to distribute pressure around a dog’s joints and hips. The foam is stated to be OEKO-TEX Standard 100 certified.
Best for: Dogs with a smaller bed whose existing cushion has flattened. Its main advantage is that it can be placed inside an existing cover, so the whole bed does not need to be replaced.
Limitation: This is foam only; a cover or waterproof liner is not included. Measure the inside of the bed cover before choosing this size.
KSIIA Orthopedic Dog Bed With Waterproof Lining
Unlike the bare foam replacements, this 35 x 22-inch KSIIA product is a complete dog bed. It has 3-inch-thick high-density egg crate foam, a soft plush sleeping surface, and a middle TPU layer intended to keep liquid from reaching the foam. Its cover has an L-shaped zipper and is machine washable.
Best for: Buyers who want a ready-to-use bed with a removable, washable cover instead of an insert for an existing bed. The waterproof layer and included foam make it a more complete option than a bare cushion.
Limitation: It is not a standalone replacement insert. Choose a different product if you specifically need foam to fit a cover you already own.
EechicSpace 36 x 24-Inch Orthopedic Foam Insert
This 36 x 24 x 3-inch insert uses 30D egg crate foam. The product features describe the foam as firm and responsive, with a shape designed to resist flattening. It is intended as a replacement for an old cushion and is listed as OEKO-TEX Standard 100 certified.
Best for: Owners replacing foam in a rectangular bed with a 36 x 24-inch interior. It offers the same stated foam construction as the smaller EechicSpace option, in a longer and wider size.
Limitation: No liner or cover is included. The foam needs a suitable bed cover, and the product listing recommends adding a waterproof liner for accident protection.
EechicSpace 36 x 27-Inch Egg Crate Insert
This replacement cushion measures 36 x 27 x 3 inches and is made from 30D egg crate foam. Its listed features emphasize firm support, pressure distribution, and resistance to flattening. The foam is stated to be OEKO-TEX Standard 100 certified.
Best for: Buyers whose bed cover needs a wider 36 x 27-inch insert. Compared with the 36 x 24-inch option, it provides three additional inches of width, so careful measurement is important.
Limitation: It is a bare foam insert, not a complete bed. A liner or cover must be sourced separately if one is needed.
EechicSpace 36 x 24-Inch Waterproof Liner
This 36 x 24-inch liner uses 95gsm polyester with a TPU layer. The product features describe it as waterproof, with liquid kept from reaching the foam. The liner can be wiped clean or unzipped and machine washed in cold water. Its fabric is stated to be OEKO-TEX Standard 100 certified.
Best for: Owners who already have foam and want a protective layer between it and the outer bed cover. The listing says it is designed to pair with EechicSpace foam inserts and fit most standard dog bed foam or mattresses.
Limitation: This is a liner, not a foam cushion. Match its dimensions to your foam; the listing advises checking the size chart.
Buying Guide: How To Choose A Dog Bed Cushion Insert
How do you choose the right size?
Measure the inside of the bed cover rather than relying only on the bed’s outside dimensions. Compare length, width, and thickness with the insert listing. A cushion that is too large may be difficult to fit, while one that is too small can leave gaps. The listed EechicSpace inserts are all 3 inches thick, but their length and width differ.
Should you buy foam only or a complete bed?
Choose a bare insert when the current cover is still usable and you only need to replace flattened foam. Select a complete bed, such as the KSIIA option, when you need both cushioning and a cover. A liner is a separate accessory for protecting foam; it does not replace either the foam or the outer bed cover.
What foam features matter?
Compare the foam’s stated construction, thickness, and support description. The EechicSpace options use 30D egg crate foam and measure 3 inches thick. KSIIA describes its bed foam as high-density egg crate foam, also 3 inches thick. These product descriptions can help narrow options, but they do not establish that a particular cushion is right for every dog.
Do you need a waterproof layer?
A waterproof layer may be useful when moisture protection is a priority. The KSIIA complete bed includes a TPU layer, while the EechicSpace liner is a separate component that fits around foam. Check whether the product includes the component you need and verify dimensions before ordering.
Frequently Asked Questions
Can you replace dog bed foam without replacing the whole bed?
Yes. A replacement insert can be placed inside a compatible existing cover. Measure the cover’s interior and confirm the insert dimensions before buying.
Are these products all complete dog beds?
No. Four products here are foam inserts or a liner. The KSIIA product is a complete bed with foam, a removable cover, and a waterproof layer.
Does a foam insert include a washable cover?
The EechicSpace foam inserts are listed as bare foam, with no liner included. The KSIIA complete bed has a removable, machine-washable cover.
Which EechicSpace insert is the widest?
The 36 x 27-inch EechicSpace insert is wider than the 36 x 24-inch and 30 x 20-inch options. Confirm that its dimensions match your bed cover.
Can the waterproof liner replace the foam?
No. The 36 x 24-inch EechicSpace product is a liner designed to surround foam. It does not provide the cushion itself.
