Next-day delivery — £49

Available on selected in-stock, bed-only orders placed before 10am, Monday to Friday, subject to postcode and availability. Saturday delivery is available in some areas; Sundays are excluded. Some Scottish locations take longer. Mattresses and additional items are excluded from this service.

Delivery and installation — £99 per bed

Normally arranged within 5–10 working days, Monday to Friday. Includes room-of-choice delivery, unpacking, bed assembly and packaging removal if requested. Installation does not include fitting or connecting a television or other electrical equipment.

Please ensure access is clear, there is enough space for assembly, and your existing bed is dismantled and removed from the installation area.

Mattresses and pre-orders

Handmade mattresses can take approximately 1–2 weeks and may arrive separately from the supplier. Pre-order estimates are shown on the relevant product page. Delivery times are estimates unless expressly agreed otherwise in writing.

Returns

For most online and telephone purchases, you can notify us of cancellation within 14 days beginning the day after delivery, then have a further 14 days to return the goods or make them available for agreed collection. You pay the direct return cost unless the goods are faulty, incorrect or misdescribed. Excessive handling, assembly or use may reduce your refund where permitted.

Exclusions apply to genuinely bespoke goods and qualifying sealed hygiene-sensitive items once unsealed. Your statutory rights remain unaffected.

For full postcode restrictions, access requirements, charges and returns information, please see our Delivery & Returns and Terms & Conditions.

Spread the cost with available options from Klarna, Clearpay and DivideBuy, part of Zopa.
