FAQ Section
What is a 4 inch memory foam mattress cover?
A 4 inch memory foam mattress cover is a thick layer of memory foam that sits on top of your existing mattress. It enhances comfort and support, often making older or firmer beds feel brand new.
Can I use a mattress protector over a 4 inch topper?
Yes! Many mattress protectors, like those listed above, are designed to accommodate thicker toppers, especially those with deep pockets or zippered enclosures.
Is a 4 inch topper good for back pain?
Definitely. A 4 inch memory foam topper offers significant contouring and pressure relief, making it ideal for people who suffer from back pain.
How do I clean a memory foam mattress cover?
Most memory foam toppers come with a removable and washable cover. However, the foam itself should be spot-cleaned only.
Does a memory foam cover retain heat?
Traditional memory foam can trap heat, but many modern covers (like gel-infused or ventilated ones) are designed to sleep cooler.
Will my sheets still fit with a topper?
You may need deep-pocket sheets to accommodate the extra thickness of a topper plus your mattress.
How long does a memory foam topper last?
On average, a good quality topper can last 3-5 years, depending on usage and care.
Do I need to air out my new topper?
Yes, it’s recommended to let your topper air out for 24-48 hours to reduce any initial off-gassing odor.
What size should I buy?
Always match the topper size to your mattress size. Queen size topper for queen mattress, twin for twin, and so on.

Yes! Pillow top pads like the EASELAND or KAYFIA add extra softness and style without affecting the benefits of the foam underneath.
