Mattress Toppers Buying Guide

A better way to choose

A mattress topper is one of the easiest ways to change the feel of your bed without replacing your mattress. While it will not fix a mattress that is badly sagging or structurally worn, it can help make a firm mattress feel softer, add a more cushioned top layer and make your bed feel more comfortable.

For many customers, a topper is the difference between a bed that simply works and one that feels more inviting at the end of the day.

The Bed Bath & Beyond range at a glance

At Bed Bath & Beyond, you’ll find a range of mattress toppers and underlays designed to add comfort, support and protection to your sleep set-up.

Choose from contouring memory foam toppers, lofty fibre-filled toppers and naturally cosy wool underlays, with selected styles available from Single through to California King.

Whether you want the pressure-relieving feel of memory foam, a plush layer of cushioning, extra warmth through the cooler months, or everyday protection for your mattress, our topper and underlay range makes it easy to create a bed that feels more comfortable, supportive and inviting.

What to consider before buying

The best mattress topper or underlay depends on what you want it to do. Some options are designed to add softness, others offer a more supportive feel, and some help with warmth and temperature regulation.

Before choosing, think about three key things: the feel you want, the size of your mattress and your budget.

If your mattress feels too firm

A synthetic or fibre-filled topper can be a simple and cost-effective way to add softness and cushioning. These styles create a loftier, more plush sleep surface and are a great option if you want your bed to feel more comfortable without changing the mattress underneath.

If you want more support

A foam or memory foam topper may be a better fit. These styles help cushion the body and reduce pressure points while you sleep, making them a good choice if you want extra comfort around areas such as your back, hips or shoulders.

If warmth is your priority

A wool underlay is a great option for customers who want natural warmth and comfort. Wool has insulating properties that help keep you cosy in cooler months, while selected reversible styles offer a lighter feel when the weather warms up.

Fibre and cluster puff toppers

Fibre toppers add softness, loft and cushioning to your bed. They suit customers who want a plush, cloud-like feel without the closer contour of foam.

They are often easier to handle than heavier foam toppers and can be a good choice for guest rooms, seasonal comfort upgrades or everyday beds that need a softer feel.

Benefits of fibre mattress toppers

• Affordable way to add comfort

• Helps soften a firm mattress

• Adds a plush, cushioned layer to your bed

• Great for everyday use or guest bedrooms

• Can help refresh the feel of your sleep set-up without replacing your mattress

Memory foam toppers

Memory foam is known for its pressure-relieving comfort and supportive feel. It gently moulds to the natural curves of your body, helping to cushion pressure points and create a more personalised sleep surface.

A memory foam mattress topper is a great choice if you want to add extra support to your mattress without making your bed feel too firm. By contouring to your body shape, it can help create a more comfortable sleep surface and support a more settled night’s sleep.

Benefits of memory foam mattress toppers

• Supportive and comfortable

• Moulds to the natural shape of your body

• Helps relieve pressure points

• Adds comfort to firm mattresses

• Creates a more personalised sleep surface

Wool underlays

A wool underlay is a great option for adding natural comfort, warmth and cushioning to your bed.

Wool is naturally breathable and temperature regulating, helping you feel cosy in winter and comfortable through the seasons. Some reversible styles include a soft wool pile on one side and a smoother cotton surface on the reverse, giving you flexibility as the weather changes.

Woolrest NZ Wool underlays are secured with four corner straps, helping them sit neatly on the mattress. Other topper and underlay styles may have different fittings, so always check the product details before buying.

Benefits of wool underlays

• Made with natural fibres

• Adds cushioning and comfort to your mattress

• Breathable and temperature regulating

• Warm in winter and comfortable across the seasons

• Helps protect your mattress while adding extra comfort

• A great choice for customers who prefer natural materials

How do I care for a mattress topper?

To help your mattress topper keep its shape and feel comfortable for longer, rotate it every few months where the care instructions allow. This can help reduce uneven wear, especially if you sleep in the same position each night.

Synthetic and fibre-filled toppers should also be aired regularly, then fluffed or plumped where suitable to help maintain their loft and softness.

Always check the care label first, as care instructions can vary by material, construction and brand.

How do I clean a mattress topper?

The best way to clean your mattress topper depends on the type of topper you have, so always follow the care label.

Some toppers may only need regular airing and spot cleaning, while others may have removable covers or specific washing instructions.

To help keep your topper fresher for longer, use a mattress protector over the top. This helps protect against everyday dirt, dust and allergens, while making your bed easier to care for.

How should I store a mattress topper?

When storing your mattress topper, keep it in a dry, dark place away from direct sunlight and moisture.

Where possible, roll or fold your topper and store it in its original packaging, a breathable storage bag, or wrapped in a clean sheet or mattress protector.

If your topper cannot be rolled or folded, cover it before storing to help keep it clean and protected.

How long does a mattress topper last?

Most mattress toppers last around 3 to 5 years, but this can vary depending on the material, how often it is used and how well it is cared for.

A topper used every night on your main bed will naturally wear faster than one used occasionally in a guest room. Regular care can help extend its life, including rotating it, airing it out and plumping or fluffing it where suitable.

If your topper has lost its shape, no longer feels supportive, or is not giving you the comfort it once did, it may be time to refresh your bed with a new one.

Care and finishing tips

Always check the depth of your mattress and topper together before buying fitted sheets. A topper can add enough height that standard fitted sheets may no longer fit properly.

Air your topper before use, rotate it regularly where suitable, and use a mattress protector over the topper to keep your sleep surface fresher for longer.
